Many thanks to Kristine Washburn for spending time with us to talk about eclipses! Here are some of the links we mentioned to in the show.

WARNING!

Permanent eye damage can result from looking at the disk of the Sun directly, or through a camera viewfinder, or with binoculars or a telescope even when only a thin crescent of the Sun or Baily's Beads remain. The 1 percent of the Sun's surface still visible is about 10,000 times brighter than the full moon. Staring at the Sun under such circumstances is like using a magnifying glass to focus sunlight onto tinder. The retina is delicate and irreplaceable. There is little or nothing a retinal surgeon will be able to do to help you. Never look at the Sun outside of the total phase of an eclipse unless you have adequate protection.

 

One safe way of enjoying the Sun during a partial eclipse--or anytime--is a "pinhole camera," which allows you to view a projected image of the Sun. There are fancy pinhole cameras you can make out of cardboard boxes, but a perfectly adequate (and portable) version can be made out of two thin but stiff pieces of white cardboard. Punch a small clean pinhole in one piece of cardboard and let the sunlight fall through that hole onto the second piece of cardboard, which serves as a screen, held below it. An inverted image of the Sun is formed. To make the image larger, move the screen farther from the pinhole. To make the image brighter, move the screen closer to the pinhole. Do not make the pinhole wide or you will only have a shaft of sunlight rather than an image of the crescent Sun. Remember, this instrument is used with your back to the Sun. The sunlight passes over your shoulder, through the pinhole, and forms an image on the cardboard screen beneath it. Do not look through the pinhole at the Sun.

Looking at astronomy in art, cruisin' the open clusters of Puppis, what do astronomers keep in their kits, some music and conversation.

Carpe Noctem - Seize the Night!

Van Gogh's "Starry Night"

Hello!

Hello to Anthony from Manchester, England! He is doing what most parents do just trying to stay one step ahead of the kid! And hello to Anthony's kids!

And happy birthday to my sister Mandy back home in Texas!

Special Viewing Project!

Globe at Night needs your help measuring and recording the amount of light pollution

Art

Van Gogh's "The White House at Night"
Munch's "Girls on a Pier"
Van Gogh's "Moon rise"

Donald Olson Marilynn Olson, his wife, and Russell Doescher Texas State University, San Marcos. Astronomer Russell Doescher confirmed that the star in "White House at Night" is actually Venus, just like in "Starry Night" and the placement of the moon. In Starry night Van Gogh actually painted the moon in the proper gibbous phase then changed it to a more romantic crescent

The Moon

-

Tonight the moon is in it's last quarter phase and shrinking daily. Which is good for all of the Messier hunters this weekend!

Grimaldi a tiny spot, sometime mistaken for a tiny sea on the western limb of the moon.
The approximate diameter of the inner rim is 140 kilometers(87 miles). The inner wall of Grimaldi has been so heavily worn and eroded by subsequent impacts that it forms a low, irregular ring of hills, ridges and peaks, rather than a typical crater rim. However there are peaks remaining that reach heights of over 2 kilometers.

Grimaldi is also a site for transient lunar phenomenon.
Image courtesy of the Lunar Republic

There was an interesting computer enhanced image of Buzz Aldrin on the Moon, I ran across it on the Bad Astronomer's Blog It has been cleaned up...a bit too much! Also thanks to Tom's Astronomy Blog I found out that the IAU has provisionally approved of naming 7 of the moon's craters after the astronauts who perished in the Columbia tragedy. Once all is said and done I will find craters; Husband, McCool, Chawla, L. Clark, M. Anderson, D. Brown, Ramon for you.

Planets

• Earth - Normally we don't mention our little planet but with our Vernal/Autumnal Equinox just passing it is worth a mention. Great Animation - showing the Earth moving around the sun through it's season. If you carefully watch the illumination of sunlight on the earth you will notice that only on the vernal and autumnal equinox does it cover the globe from pole to pole. It also has the arctic and antarctic circles mapped so you can see the difference between equinox and solstice.
• Venus - The brightest planet visible this month. Venus is outstanding in the Eastern morning sky and you will want to grab a pair of binoculars or even just a finder scope to check out her phase. Just over half full she is intensely bright in her gibbous phase.
• Jupiter - The largest planet resides in the confines of Libra and is highest around 3:am on the ecliptic between the bright Spica to the west and the ruddy Antares to the east. Any telescope can reveal its two widest cloud bands to you, along with its four Galilean satellites.
• Saturn - It appears as a yellowish star that rivals Capella in brightness, A small telescope will always show Titan, Saturn's largest and most extraordinary moon. A 6-inch telescope will begin to show the orange color of its atmospheric haze.
• Mars has swung past Aldeberon and is almost between the tips of the bulls horns.
• Mercury - by this weekend and on into next week start looking for the re-appearance of Mercury as a morning planet. Just south of east about 25 degrees from Venus (towards the horizon and easterly) if you remember how to measure 25 degrees, it is the spread between your pinky and thumb when fully extended. Show #10 has our primer for measuring distances in the sky

Tools/Gadgets

What do you keep in your telescope kit? Do you have too much, too little? What is your favorite tool?
Alice's telescope box

• Telrad
• lenses
• lens cleaner(brush/lens pen)
• canned air
• all the telescope bits
• red led flashers
• red flashlights
• My binder (star charts, various lists I'm working on, telrad Messier charts)

Alice's reference box

• All the Sky Spot Telrad Finder Scope books
H.E. Ray's books of constellations (both)
• several different reference books depending upon the season and the reason for the outing.\
• 6 planispheres different varieties
• flat panel red light viewer - Light Wedge
• extra batteries (AA AAA etc)
• extra red flashlights
• tools (screw drivers, adjustable wrench, duct tape, clear tape, small bolts with wing-nuts, wire, etc)

At home

• Sky Atlas - desk set in white
• Loads of books!
• Computer

What I would love to build!!

• Eyepiece bench - I like this layout - don't have that many eyepieces!! But he has great directions for drill/cutting foam. I really like how he organized his filters.
• An observing chair, something like this
• A binocular mount, something like this

Clusters

Globular - Globular clusters are gravitationally bound concentrations of approximately ten thousand to one million stars. They populate the halo or bulge of the Milky Way and are believed to be very old and formed from an earlier generation of stars. Hayden Planetarium has a great simulation on the life of a globular cluster

Open cluster - Open (or galactic) clusters are physically related groups of stars held together by mutual gravitational attraction. They are believed to originate from large cosmic gas/dust clouds in the Milky Way, we can observe the formation of new young open star clusters. You can easily see this nebulosity in the Pleiades.

There are two types of descriptors you will see with open star clusters. There is the Shapley index (Harlow Shapley)
c - very loose and irregular
d - loose and poor
e - intermediately rich
f - fairly rich
g - considerably rich and concentrated

The more detailed and specific Trumpler index/rating which is broken into 3 parts + optional nebulosity note.

The first part is a Roman numeral that denotes concentration

I - Detached; strong concentration toward center
II - Detached; weak concentration toward center
III - Detached; no concentration toward center
IV - Not well detached from surrounding star field

The second part is a Arabic number to show the range in brightness

1 - Small range in brightness
2 - Moderate range in brightness
3 - Large range in brightness

Thirdly a letter to represent the richness of the cluster

p - Poor: Less than 50 stars
m - Moderately rich: 50 to 100 stars
r - Rich: More than 100 stars
If there is an nebulosity in and around the cluster there will be an "n" attached to the end.

I give you both since you will find both used in the different resource on the internet or on star charts.

Binocular/Telescope viewing
Open Clusters
NGC images courtesy of the Chinese Public Understanding of Science website (NGC)
NGC 2451 (mag 2.8) next door to...
NGC 2477 (mag 5.8) these together show you how differnt open clusters can be!

M47 ( NGC 2422 - mag 4.4) he Sky Catalog 2000 gives an estimated age of 78 million years for this stellar swarm which is receding from us at 9 km/sec. A bright cluster in Puppis, easily visible as a hazy patch to the naked eye. Binoculars will show a large hazy patch with many stars resolvable.
M46 (NGC 2437 -mag 6.0 )This cluster is right next to M47 and is also visible to the naked eye. In binoculars M46 appears as a large hazy patch with no stars resolvable, giving a nice contrast to M47. In telescopes at low powers this cluster evenly fills the eyepiece. While you are here go to medium or high power and look for the planetary nebula NGC 2438. It will appear as a faint uneven ring, with a blue/green color.

M48 (mag 5.8) in Hydra

Not to ignore the far N. Hemisphere try
M67 (NGC 2682 - mag 6.1) in Cancer
Mel 111 in Coma Berenices (mag 1.8) P.J. Melotte had cataloged it in his 1915 catalog as No. 111. One of Potolomy's first catalogued clusters. The Coma star cluster is currently neither approaching nor receding from us, i.e. it moves tangentially to us with a velocity. (see map in Constellation section)

Constellations

Coma Berenices, Berenice's hair - One of the last of the ancient constellations. Queen Berenice sacrificed her beautiful hair to the goddess Aphrodite in order to assure the safe return of her husband from battle. Upon his return the king demanded to be shown her hair. In order to save his own life(for the hair had been stolen) the temple priest related how Aphrodite was so moved by the sacrifice removed the hair and placed it into the skies as a constellation. Coma Berenices is a small, faint constellation that can be found immediately to the east of Leo.

News

There are so many great space and astronomy news sites out there I won't try and duplicate them all, I'll just report things that really strike my fancy or that I think you might be interested in. Here is a list of some of the sites I visit daily:

• NASA's Eclipse Page -
• Great Animation - showing the Earth moving around the sun through it's season. If you carefully watch the illumination of sunlight on the earth you will notice that only on the vernal and autumnal equinox does it cover the globe from pole to pole. It also has the arctic and antarctic circles mapped so you can see the difference between equinox and solstice.
• Wiki fun- This has very little to do with astronomy but have you ever tried entering a date, like March 22, in Wikipedia. It will list world events and personalities who share that date.

Music

Hans York -"Listen to the Moon"
Radoon -"From the Moon"

Branching out to things not Messier, following the water, wondering why comets are birthed in the furnace and the fridge, enjoying some music and, of course, your company.

Carpe Noctem - Seize the Night!

Simon Vouet, The Muses Urania and Calliope, c. 1634
Urania (heavenly) is the muse of astronomy and astrology.
Calliope (beautiful-voiced) is the muse of epic poetry.

The Star-Splitter
by Robert Frost

You know Orion always comes up sideways.
Throwing a leg up over our fence of mountains,
And rising on his hands, he looks in on me
Busy outdoors by lantern-light with something
I should have done by daylight, and indeed,
After the ground is frozen, I should have done
Before it froze, and a gust flings a handful
Of waste leaves at my smoky lantern chimney
To make fun of my way of doing things,
Or else fun of Orion's having caught me.
Has a man, I should like to ask, no rights
These forces are obliged to pay respect to?"
So Brad McLaughlin mingled reckless talk
Of heavenly stars with hugger-mugger farming,
Till having failed at hugger-mugger farming,
He burned his house down for the fire insurance
And spent the proceeds on a telescope
To satisfy a life-long curiosity
About our place among the infinities.

--first stanza

Welcome!

I know it is a little late, but happy Pi day. March 14th at 1:59 UTC can be fudged into 3.14159. In our department we celebrate the notorious number 3.14.59 with Pie of course, any excuse for a party!

To make thing even better it was Albert Einstein's birthday as well.

Another anniversary to celebrate is On this day in 1926, Robert Goddard launched the first liquid-fuel rocket.

Planets

• Venus - The brightest planet visible this month. Venus is outstanding in the Eastern morning sky
• Jupiter - The largest planet resides in the confines of Libra and is highest around 3:am on the ecliptic between the bright Spica to the west and the ruddy Antares to the east. Any telescope can reveal its two widest cloud bands to you, along with its four Galilean satellites.
• Saturn - It appears as a yellowish star that rivals Capella in brightness, but in the constellation of Cancer (1 1/2 thumb width west of The Beehive - M-44) A small telescope will always show Titan, Saturn's largest and most extraordinary moon. A 6-inch telescope will begin to show the orange color of its atmospheric haze.
• Mars is sneaking it's way closer to Aldeberon creating another eye for the bull. So in that part of the sky it is hip to be red, red Beetleguese, orange Aldeberon and the red Mars
• Mercury - hidden in the glare of the sun as are Uranus and Neptune

Tools

Catalogues -

• Uranography - The branch of astronomy concerned with mapping the stars, galaxies, or other celestial bodies.
• Uranometria - The sky atlas compiled by Johann Bayer in 1603
• Messier catalogue- compiled by Charles Messier
• New General Catalogue (NGC)- compiled by John Dreyer
  IC I published in 1895 added 1,529 new star clusters, nebulae, and galaxies
  IC II published in 1908 listed a further 3,857 objects
• NGC 2000.0 - is a modern compilation of the New General Catalogue, the Index Catalogue, and the Second Index Catalogue
• HIP - Hiparcos catalogue - Its name is an acronym for High Precision Parallax Collecting Satellite and was chosen for its similarity to that of the Greek astronomer Hipparchus.
• Caldwell and Herschel 400 and Uranometria - all great astronomy catalogues

Constellations

Volans, the Flying FishOriginally named Piscis Volans, this constellation was named by Johann Bayer. It is located where all good fish should be, below a boat. In the southern sky Volans is southwest of Carina, the keel, and east of the Large Magellanic Cloud. Johannes Kepler called this set of stars Passer, the Sparrow.

Camelopardalis(ka-MEL-oh-PAR-duh-lis), the Giraffe can be found between Perseus, Auriga and Ursa Minor. This constellation was first observed to look like a camel but name was eventually changed to camelopardalis, which is Latin for giraffe. In the winter months the giraffe appears upside down. Only during the summer months does it appear right side up.

The Moon -

This weekend the moon will be moving from a full moon to a waning gibbous so your early evenings will be darker.

Mare Crisium (Sea of Crisis) will slowly be covered by lunar night as this week continues so we are going to look at the NW quadrant of the moon.

Mare Frigoris (Sea of Cold) slices across the northern cap of the moon and at it's western end seems to dump into Sinus Roris.

Image courtesy of the Lunar Republic

Sinus Roris (Bay of Dew)leads into the great Oceanus Procellarum (Ocean of Storms). This ocean of regolith sweeps down the western side of the moon.

Last week we looked at the craters Copernicus and Kepler, this week our lunar crater is in the great ocean further north, but just as bright as Kepler. Crater Aristarcus

Image courtesy of the Lunar Republic

We are actually looking at a complex of Aristarcus a Greek grammarian noted for is commentary on the Iliad and the Odyssey and just a little bit SW Herodotus named after the greek "Father of History". Squiggled above and between them is Valles Schoteri. To see Herodotus or Schoteri will take a telescope. At the southern edge it finally meets up with Mare Humorum (Sea of Moisture) and Mare Congnitum (The Sea that has become known)

Naked eye viewing-The splendid open cluster IC 2602 is still known under the common name "Southern Pleiades." An open cluster of more than 50 stars in the constellation Carina, centered on the blue-white star Theta Carinae and can be seen with the naked eye. (use the chart below)

Binocular viewing Kemple's Cascade

Kemble�¢ï¿½ï¿½s cascade is situated in one of the most difficult constellations to detect in the night sky, Camelopardalis or the Giraffe. A string of 15 to 25 stars ranging from the 5th to the 9th magnitude. The stars seem to cascade from the northeast down to the southwest they do not form a group or cluster physically, it's only a chance arrangement of stars. At the southeastern end of the chain of stars you will find the 6th magnitude open cluster NGC 1502, containing 15 stars in a 7' area.

Eta Carina - The Eta Carina Nebula is the largest diffuse nebula in the sky, much larger than the more famous Orion Nebula. The star Eta Carinae itself is also interesting. It is a variable star; in the mid-19th century it was the second brightest star in the sky; today it is not even visible with the naked eye.

News

There are so many great space and astronomy news sites out there I won't try and duplicate them all, I'll just report things that really strike my fancy or that I think you might be interested in. Here is a list of some of the sites I visit daily:

• Planet Quest - the counter has moved up from 159 to 160 extrasolar planets. Starting in 1991 with Pulsar 1257 but more popularly realized with 51 Pegasi in 1995 the list now seems to have grown to 160 (plus a few others in waiting ) with the last addition residing in Sagittarius. Still getting the data in.
• Enceladus - "Our search for liquid water has taken a new turn. The type of evidence for liquid water on Enceladus is very different from what we've seen at Jupiter's moon Europa. On Europa the evidence from surface geological features points to an internal ocean. On Enceladus the evidence is direct observation of water vapor venting from sources close to the surface," said Dr. Peter Thomas, Cassini imaging scientist, Cornell University, Ithaca, N.Y.

  But in the mean time, scientist who believed that Enceladus was fueling Saturn's E ring now have further proof!

• Stardust Update - Comets, they said, may not be as simple as the clouds of ice, dust and gases they were thought to comprise. They may be diverse with complex and varied histories. Wild 2 seems to be an example of that complexity.

  Remarkably enough, we have found fire and ice," said Donald Brownlee, Stardust principal investigator and professor of astronomy at the University of Washington in Seattle. The returned samples show high-temperature materials from the coldest part of our solar system.

  The material like that in the green Hawaiian beach sand is called olivine. Its presence in the comet's dust trail was a surprise. "It seems that comets are �¢ï¿½�¦ a mixture of materials formed at all temperatures, at places very near the early sun and at places very remote from it," said Michael Zolensky, Stardust curator and co-investigator at JSC

• Martian crater flyby - A "Grand Canyon of Mars" slices across the Red Planet near its equator. This canyon -- Valles Marineris, or the Mariner Valley -- is 10 times longer and deeper than Arizona's Grand Canyon, and 20 times wider. As the picture shows, you could drop the whole Los Angeles basin into a small part of Valles Marineris and leave plenty of room to spare. In length, the canyon extends far enough that it could reach across the United States from East Coast to West Coast, while its rim stands more than 25,000 feet high, nearly as tall as Earth's Mount Everest.

Just how many ways can you think of to tell time?

Carpe Noctem - Seize the Night!

 Canis Major

The great Overdog
That heavenly beast
With a star in one eye
Gives a leap in the east.
He dances upright
All the way to the west
And never once drops
On his forefeet to rest.
I'm a poor underdog,
But to-night I will bark
With the great Overdog
That romps through the dark.

-- Robert Frost 

Welcome!

Welcome to Brian from Minnesota, Dave from Alabama and Pat from Montreal and thank you for the email.

Hello to Bill from Missouri who sent me a very nice note and also hello to his son who will be starting his Astronomy Merit badge soon! Remember, if it is a nice night out then you have an excuse to go outside and stay up late...as long an you are learning those constellations....and your homework is done!

Tips and Tricks - Time!

"Tiiiiiiime is not on my side...no siree!"

Local Apparent Time (LAT), also called apparent solar time or sundial time. Noon was what most people still think is noon: when the Sun crosses the meridian or the highest point in its path.

Your Local Mean Time (LMT) Astronomers created an imaginary, "averaged" Sun that travels along the celestial equator. Differs from your standard civil (clock) time by many minutes. The correction depends on how far you live east or west from the center of your time zone.

Standard time. Time zones are standardized on certain longitudes: 75 degrees W for Eastern Standard Time, 90 degrees for Central, 105 degrees for Mountain, and 120 degrees for Pacific. For every degree you are east of your time zone's standard longitude, add four minutes to standard time to get LMT. For each degree you are west, subtract four minutes. The number of minutes the real Sun lags behind or runs ahead of the mean Sun was named the equation of time.

Summer-time To obtain daylight saving time ("summer time"), subtract one hour from standard time.

Universal Time (UT). Standard time (and its daylight-saving variant) serves fine within a given time zone. But when a time applies worldwide, such as in an astronomical almanac, you need one reference point. Logically enough, the "universal" time zone that was agreed upon (in 1884) is that of 0 degrees longitude. This longitude is, by definition, that of a line engraved in a brass plate in the floor of the Old Royal Observatory at Greenwich, England. UT is often called.....

Greenwich Mean Time (GMT). Greenwich Mean Time" or UT1, until the popular meaning drifted to match UTC. Astronomers now try to avoid the term altogether unless they are waxing nostalgic. Adding to the confusion, GMT began the day at noon, not midnight. .

Coordinated Universal Time or UTC, Since 1967 the second has been defined as how long cesium-133 atoms take to emit 9,192,631,770 cycles of a certain microwave radiation in an atomic clock. To keep our clocks in close step with the turning of the Earth, a leap second is inserted into Universal Time when required - about once a year on average. A leap second may be added at the end of June 30th or December 31st UT, giving the last minute of the chosen day 61 seconds.

The result is the system by which all the world's clocks are set. UTC is the basis for all time-signal radio broadcasts and other time services.

Civil twilight - when the Sun's center is 6° below the horizon the brightest stars are visible and at sea the horizon is clearly defined.

Nautical twilight - when the Sun's center is 12 degrees below the horizon this would be the "dark" to obey in the mother's order to "be home before dark"! For nautical purposes it is that time when the horizon ceases to be clearly visible and it is impossible to determine altitudes with reference to the horizon.

Astronomical twilight - when the Sun's center is 18 degrees below the horizon and there is no sun glow left at all.

John Harrison (March 24, 1693 - March 24, 1776) an English clock maker, who designed and built the world's first successful maritime clock, one whose accuracy was great enough to allow the determination of longitude over long distances.

Sky and Telescope article on Time

Planets

Venus - just before dawn between Aquila and Sagittarius
Jupiter - in the wee hours of the morning in the constellation Libra. On the 5th of this month it stopped moving across the sky relative to the background stars and began its westward motion or retrogradation.
Go check out the finder forTransit of the Great Red Spot and a JAVA script to help you find Jupiter's moons
Saturn - is in Cancer the crab and come summer we should see that planet slow down and turn around as well.
Mars - in Taurus between Aldeberon and the Pleiades and speeding right along

Naked eye viewing- Moon is a waxing gibbous and becomes full on the 14th (don't forget the penumbral eclipse!) Mare Frigoris is the long narrow strip of a sea across the lunar N.Pole
Right below Frigoris is Mare Imbrium (IM-bree-um - Sea of Rains) the second largest sea.
Craters Kepler and Copernicus run along just above the equator (I"m trying to create a picture so check back soon!)
and Mare Insularum(Sea of Islands) and Mare Nubium (NEW-bee-um)run below Copernicus.

Binocular viewing- looking for comets!
