Saturday is not only our in-Monrovia sidewak astronomy viewing night,
but it is also the Winter Solstice! So in the spirit of the season, I
updated a familiar poem for your reading pleasure. Hope you enjoy it
By the way, the weather forecast calls for mostly clear and a low of 38
degrees Friday night, and partly cloudy and 41 degrees Saturday night.
So at this time we are still planning both nights 7-9 p.m. Now back to
the solstice! Jane
Inspired by the poem /A Visit From St. Nicholas/, written by Major Henry
Livingston, Jr.
Twas the night before Solstice, when all through the city,
Not a planet was visible, now isn't that a pity.
The telescopes were stored in the garage with despair,
In hopes that the weather would soon turn to fair.
The astronomers were nestled all snug in their beds,
While visions of nebulae danced in their heads.
And Mojo with his laptop and I with my starmap,
Had just settled down for a cloudy night nap.
When out on the lawn there arose such a clatter,
I sprang from the bed to see what was the matter.
Away to the window I flew with a flash,
Tore open the shutters and threw up the sash.
The moon shone so brightly, no clouds hid the glow,
The full moonlit lustre to objects below.
When what to my wondering eyes should appear,
But Pleiades, Orion, and Ursa Major, the bear.
With our trusty old telescopes, the setup was quick,
I knew in a moment we had objects to pick.
More rapid than eagles, the targets they came,
We aimed and we pointed and called them by name.
"Now, Procyon, now Pollux, now Castor and Capella!
On Aldebaran, on Rigel, on Sirius, and Betelgeuse, the red fella :-)
To the top and around the winter circle of stars,
Now a quick look at luna, then Saturn and Mars.
As fireflies that before the dawns morning light,
Brilliantly flicker and soon are a memory bright,
A new wonder would paint the dark sky to pale blue,
The sunrise was nearing and morning twilight was too.
And then in a twinkling, I heard on the roof,
The prancing and pawing of each little hoof.
As I stepped from the telescope and was turning around,
Down the chimney the stranger came with a bound.
He looked like an astronomer, bundled from head to his foot,
Like a stargazer his clothes were tarnished with ashes and soot.
A bundle of toys he had flung on his back,
Looked just like our telescope accessory pack.
His eyes - how they twinkled! his dimples how merry!
His cheeks were like roses, his nose like a cherry
He looked like we do after a cold winter starshow
Freezing but happy from the Milky Way glow.
The stump of a flashlight held tight in his teeth
Its soft red glow encircled his head like a wreath
We asked him if he'd ever looked closely at Mars
"I'm working at night, I've no time for the stars".
He stepped up to the eyepiece, a right jolly old elf,
And I smiled as he gasped, in spite of myself.
A wink of his eye and a twist of his head,
Soon gave me to know I had nothing to dread.
He spoke not a word, but took in view after view,
Then he spoke with a sigh he had more work to do.
And laying his finger aside of his nose,
And giving a nod, up the chimney he rose.
He sprang to his sleigh, to his team gave a whistle,
And away they all flew like the down of a thistle.
But I heard him exclaim, ere he drove out of sight,
Happy stargazing to all and to all a dark night.
My apologies to Major Henry Livingston Jr. 1748 - 1828, author of /'Twas
the Night before Christmas/ or /Account of a Visit from St. Nicholas/.
Previously believed to be the written by Clement Clarke Moore.

Yesterday, December 18th Mars reached its closest approach to Earth,
and 6 days later, on December 24th is Mars Opposition. This year
Mars is 55 million miles from Earth at closest approach. This month
and next month too both offer outstanding views of Mars, but by late
January Earth pulls away from Mars and the best viewing window ends
in mid-February. So we've added some extra sidewalk astronomy
viewing nights to the Old Town Sidewalk Astronomers schedule. We may
add more, too, so keep looking for these little notes from us.
Join us, weather permitting, in Pasadena, on Colorado Blvd somewhere
between Fair Oaks and Pasadena Avenues Friday night December 21 and
Saturday night at Monrovia's Library Park at Myrtle and Lime Streets
(less room for the next 2 years due to library construction
fencing). The current forecast calls for mostly clear both Friday
and Saturday nights. Do check out website for any weather changes.
If the mostly clear conditions change to mostly cloudy, we would
probably cancel and reschedule. Expect cold temperatures (high
30's/low 40's) this weekend - it'll be even colder - in the 20's on
Mt. Wilson! Both of these events will get started a little later so
we can show Mars higher in the sky. Plan on telescope viewing from
7:00 - 9:00 p.m. We probably will not arrive until then. By 9:00
p.m. we may be too cold to continue. Our Sidewalk Astronomers
founder, John Dobson, is fond of saying "many are cold, but few are
frozen". :-)
Each Mars opposition, Zolt Levay from the Space Telescope Science
Institute updates the excellent Hubble telescope "Mars close
encounters comparison chart ". And he updated it just today. I hope
you enjoy it - it really helps to show the apparent size of Mars each
year.

JPL has a Mars Opposition feature today too, it's great, especially
the Mars Rotation video, and a link to the monthly What's Up Video.
:-) http://www.jpl.nasa.gov/news/features.cfm?feature=1560
I hope to see you on the chilly sidewalk this weekend. We only see
our red neighbor on its approach to Earth every two years, and Mars
won't be this close to Earth again until 2016. I'll be handing out
some very special NASA Mars lithographs this weekend, while the
supplies last.
Want more Mars? Visit my Mars page: http://www.otastro.org/Mars2005/
Finally, speaking of John Dobson, you might enjoy listening to
astronomer Bob Cesarone's song about John Dobson, called "Telescope
Man". Bob's band, Northern Cross recorded the song a couple years
ago, and he gave a copy of it to John (and to us) late last year.

Step outside this month, look up in the east, and you'll be in for a
real treat! Mars is really bright and easy to view. That's the
topic of this month's What's Up: Mars! It's as big and as bright as
it will get this month, and it won't be this great a view again until
2016! What's Up here:
http://education.jpl.nasa.gov/amateurastronomy/index.html
Tonight, I stepped outside of my San Francisco hotel, walked a few
feet to Union Square, and looked East down Post Street and there was
Mars high in in the cloudless sky. Mars is easy to see from the
city, the backyard, everywhere. Have a look!
This weekend, the Old Town Sidewalk Astronomers will be showcasing
Mars and the moon from Monrovia on Saturday December 15. We'll be
out again Dec 21 in Pasadena and Monrovia December 22, weather
permitting.

Our good friends and associates from the San Francisco Sidewalk
Astronomers have published an excellent guide to buying telescopes, in
the spirit of the season.
I'll be adding a link from the Old Town Astronomers site, meanwhile you
can enjoy the article here:

I know some of you won't see this until tomorrow -- sorry!
If you peek outside tonight, Monday, and find the moon -- that bright
red pumpkin-colored star right next to it is Mars.
Cheers,

This coming weekend is our public astronomy weekend in Pasadena and
Monrovia. Mojo and I will be setting up telescopes on Colorado Blvd in
Pasadena, CA - some place between Fair Oaks and Pasadena Avenues from
5:30 until 9:30 p.m. Friday the 16th.
Saturday the 17th is our Monrovia night - corner of Myrtle and Lime
Streets in Monrovia, CA as usual, from 5:30 until 9:30. Saturday is
also the peak of the Leonid Meteor shower. I doubt anyone wants to hop
in a car and drive to a dark location but I am bringing it up, just in
case.
The Meteor fluxtimator http://leonid.arc.nasa.gov/estimator.html tells
us that the time to view is from 3:00 - 5:00 a.m. Sunday Morning and
the rates will be about 4 - 8 meteors per hour. That's not a lot, but
if you enjoy getting out of the city lights this would be a great
weekend to do it. We'll stay in town, show the moon, skip the Leonids,
unless from the back yard.
Here is the forecast for the Leonids: http://leonid.arc.nasa.gov/
Here's the weather forecast (good for moon viewing):

When you look at Mars, have you ever wondered where the rovers are at
that moment? I do, and it adds to the fun of looking at Mars when I
know the rovers are facing Earth as I am looking up at that bright
ruddy planet. Wow is it ever getting bright!
Where and when to see the Rovers is part of the topic of my
November's What's Up. That and how to find a wonderful star, Mira,
which was captured in a fascinating image by the Galaxy Evolution
Explorer in August. Connecting stargazing to NASA missions adds some
complexity and extra enjoyment, at least it does to me. I hope you
enjoy this one!
Here is the What's Up:

Next sidewalk astronomy is November 16 and 17th
http://www.otastro.org/ Have a look at Comet 17P/Holmes. If history
repeats, it will only stay bright for 20-30 days. That is what
happened in 1892 when it was discovered. And we're on day 16 now!

I am not much of a morning person, but tomorrow
morning - that's Wednesday the 7th there is a
shuttle +ISS pass over the Pasadena area. The
two spacecraft will be visible in the same part
of the sky as the bright comet 17P/Holmes in
Perseus. That should make a very pretty picture.
(if it is foggy, well, then I am sure someone
will have a very pretty picture of this lineup)
A friend here at work drove up CA Route 2, just a
couple miles up got him above the fog this
morning, where he snapped a photo of the shuttle
and International Space Station. Then he emailed
it to one of the astronauts aboard the shuttle
today.
Here is the chart
http://www.heavens-above.com/PassDetails.asp?Session=kebgcaianecpbahhnoafgb…
Here are the details: Look to the North East at
5:00 a.m. (not P. M.) - this allows a few
minutes to get oriented. It's a short pass just
3 minutes from 5:07 to 5:10 a.m. The two
spacecraft travel from NW to NNE 33 degrees above
the horizon. Then you should take a look at the
planetary lineup. Strung along the ecliptic will
be (starting from the Eastern horizon: Mercury,
the moon, Venus, Saturn and Mars (almost
overhead). Now that's what I call a lineup!
Date: Wednesday, 07 November, 2007
Observer's Location: Pasadena ( 34.1480°N, 118.1440°W)
Local Time: Pacific Standard Time (GMT - 8:00)
Leaves shadow 05:07:38 33 degrees above horizon
Maximum altitude 05:07:44 33 degrees above horizon
Drops below 10° altitude 05:10:24
Sets 05:12:30
There is another pass at 5:30 a.m. on the 8th,
but it only is 12 degrees above the horizon.

Normally on the third quarter moon weekend, you don't find the Sidewalk
Astronomers setting up. There will be no moon in the early evening.
But the sky gave us a big surprise late in October.
Normally extremely faint, comet 17P/Holmes had an outburst that made it
a million times brighter -- bright enough that we can see it from
downtown Monrovia without a telescope!
Over the past couple of weeks, amateurs and professionals alike have
been watching the comet's coma, the glowing cloud of dust that surrounds
it, grow in apparent size.
It's a fun object to see in a telescope, and we invite you to join us
this Saturday evening in Old Town Monrovia to do exactly that. We'll be
in our usual spot, at the corner of Myrtle & Lime, from 7:30 'til 9:30 p.m.
Because the comet is fairly far to the north in the sky, whereas the
moon and planets are usually found to the south, we'll have to move a
little up the walk towards the Mark Twain statue to get a clear view
without a tree in the way.
Right now the weather forecast looks good for Saturday night. I'll send
a follow-up note if that changes.
More about the comet and links to other pictures can be found on JPL's
web site here: <http://www.jpl.nasa.gov/news/features.cfm?feature=1514>

Do you need some eerie sounds to spook the little ghouls and goblins
tonight? Why not play the Eerie and Bizarre Sounds of the Saturnian
System. http://saturn.jpl.nasa.gov/multimedia/sounds/ ? Included
are sounds of Enceladus, echoes from Titan's surface, speeding
through Titan's haze, and sounds from the Lord of the rings, Saturn!
There are even more spooky sounds of our solar system on the JPL
webpage today http://www.jpl.nasa.gov/index.cfm look on the New
Multimedia section.
And if you want to see a ghostly interloper in the sky tonight, take
out the binoculars and see a comet from your own front (or back)
yard! Here's where to look:
http://www.jpl.nasa.gov/news/features.cfm?feature=1514 To the unaided
eye, the comet looks like a fuzzy star, but in binoculars (or
telescopes) it looks like a ghostly snowball with a bright center,
much like the image shown on the link above. It was taken by Gary
Spiers, who is one of our sidewalk telescope gang in Monrovia.
Congrats on the picture!
"To see the comet, all you have to do is step outside and look to the
Northeast. You should be able to see the "W" that is the
constellation Cassiopeia - it's standing on its end. One and a half
"fists" away to the right is a bright star in the constellation
Perseus. You probably won't be able to see all the Perseus stars, but
the bright one - Mirfak - should be visible. It marks the top of a
triangle, which is about the size of your thumb held at arms length
away. The triangle's lower left corner is the comet!".
We may set up telescopes for a special comet viewing night Saturday
the 3rd. Stay tuned, we'll send an announcement if that plan firms
up.
October What's Up is about tricks and treats in the night sky. It
starts out with some of those spooky sounds from the solar system.
