With the latest storms we know that winter is upon us. Now is when we measure our true devotion (or obsession depending on point of view) with the hobby of astronomy. Who is determined to brave the cold for a winter crisp look at the sky? When I slither through three miles of icy mud to find Pat and Aileen Hiemann parked on the old airstrip at Empire with their trailer waiting for the clouds to clear, I know the answer... Some of us are that crazy.
The club holiday party was a wonderful event with much celebration of friends and comrades in the hobby, discussing the years events and looking at future projects. David Levy gave a wonderful talk and tribute to past friends. He also announced that the club raised the most money for the MDA telethon at last year's Telescopes for Telethon event and will receive a new Meade 10" GPS telescope. We will again support David and Wendee in this event with a public star party at Sabino Canyon, this year scheduled for April 19th, and a backup date of the 20th.
The calendar for the next year has been published and we are preparing another good year. Again we have two Kitt Peak picnics planned, one spring and one fall, as well as two large public events at the Desert Museum, Mar 16 and Oct 5th. We have yet to completely pin the Park Service down on the Grand Canyon Star Party, but the dates should be June 8-15th, watch for further announcements.
The club has also inaugurated an e-mail list to be used for general announcements. Many thanks to Terri Lappin for setting this up. Look for an e-mail invitation to join. Is is completely opt-in, if you do not respond to the invitation you will not get mail from the list. Only club officers and a few select others can post to the list so it shouldn't flood your in-box, but it can be used to get information out to the membership that is more time sensitive than the newsletter.
We have much to be thankful about this year. The sky has bestowed a bounty of wonderful events this year, eclipses, comets, and meteors. A good year for the hobby, and a good year for us. I hope 2002 be just as wonderful.

Beginners Lecture
The Astronomical Catalogue
Speaker: Andrew Cooper
How do we know what is where in the sky? The history of this basic tool of astronomy, From Hevelius, Flamsteed, and Messier to Hipparchus.
Main Lecture
Tales of a Cold Universe: The Birthplaces of Stars and Planets
Speaker: Craig Kulesa
A long time ago, in a part of our Galaxy far away, a star was born. That star was our Sun, 4.6 billion years ago. Despite our proximity, our knowledge of the formation of our Sun and its host of planets is surprisingly incomplete. In this talk, we will explore the dark, cold places of the Galaxy where stars are born, cocooned and enshrouded from our view by walls of dust and molecular gas. We will learn whether the ingredients that comprise our own Solar System are also being used to build new ones today. In search of answers to these timely questions, we will dissect infrared and sub-millimeter light from the sites of star and planet formation, which will take us from Kitt Peak all the way to observatories at the South Pole.
Craig Kulesa is a finishing PhD student at Steward Observatory. Craig spoke to us in June 2000 about the various tools that professional astronomers have at their disposal for studying the nature of the universe. He presented an excellent lecture back then and we've again asked him to lecture to us. He is currently working at the South Pole, so we wish him good weather and a safe trip back to the states.
Member News
We welcome the most recent members who have joined the TAAA: Dr Richard Belli, Gary and Megan Chaplin, Mark Daniels, Russell Frank, Terry Shipp and returning members Alex Gibbs and Andrew Tubbiolo. Glad to have you join! If you haven't already, be sure to pick up a new members pack at a meeting. Hope you'll make it to our star parties or meetings so we can all get to know you.
Calendars for 2002
There are still some 2002 calendars left for purchase. The price is $10 each (~$2 off the regular selling price), or $9 each for more than one. Our supply is getting smaller and smaller. The calendar, which features a full-color astronomical photo, image, or painting each month, has daily information about astronomical events, both historical and observational...plus space for adding important events you need to remember. Please see Ann Scott at a meeting if you want to purchase a calendar.
Proceeds from the sale of these calendars will be used appropriately as decided by the board. Thank you to all who support the TAAA through the purchase of the yearly calendars.
"Oh, What a Night!"
By John Kalas
This seemed to be the sentiment of the sixty TAAA Members who attended the Holiday Party on Friday, Dec. 14th. Held in the Rillito Room at the Tucson Racquet & Fitness Club, the event was a resounding success; good food, good fun & good friends. Special invited guests for the evening were David and Wendee Levy and Ed and Pat Vega. Unfortunately, Ed and Pat were unable to attend. The efforts of Liz Kalas, Twila Peck, Sheila Conrad, Terri Lappin and Thom Peck were appreciated by all. The room was nicely decorated with strings of holiday lighting and festive table decorations designed and set out by Liz, Twila and Sheila. Trays of appetizers preceded a delicious chicken dinner topped off with gourmet cookies (the chocolate chip were to die for).
Following the dinner, the attendees were treated to several fascinating presentations. The keynote speaker was David Levy who gave an inspiring talk and slide presentation about the "Mentors I have known". He concluded his talk by running his slides timed to the song "This Side of the Moon" by the group Alabama; a very poignant and artful finale followed by the loud applause of appreciation. Wayne Johnson gave a nifty interactive talk reviewing the special astronomical events of the year and some supernova news. Ed Finney and Robert Crawford showed some spectacular Leonid Meteor slides and shared their photography secrets on how they achieved such fantastic shots. TAAA President, Andrew Cooper, gave a slide presentation reviewing some of the accomplishments of the club this past year, emphasizing the tremendous volunteer efforts of our members. Roger Tanner presented an impressive animation of CCD images taken by he and Steve Peterson of Comet Linear moving through a star field.
Another "fun" part of the activity was the door prize raffle. John Kalas reviewed the 27 terrific gifts that were donated by seven stores or individuals. Starizona supplied the computer astronomy program Starry Night Pro with several great books. Sky Works donated ten items including: the Sky Map Pro and The Sky astronomy programs, a pair of Meade 7x50 binoculars, a Meade Electronic Eyepiece and a Moon broach. Stellar Vision donated four $20. gift certificates. TAAA Member Pat Heimann, maker of ChartMarkers, supplied a Telrad finder. David and Wendee Levy brought three "Let's Talk Stars" tee shirts and two copies of their book "Making Friends With the Stars". The Discovery Channel Store in the Park Place Mall donated a Meade Electronic Eyepiece and a book. The Nature Company in the Tucson Mall supplied an astronomy book. Everyone thoroughly enjoyed the raffle and appreciated the support of the donors. It was a fun night.
Club Logo Jackets
Advance sales will be made during the January meeting for light-weight jackets with the TAAA club logo. Delivery is expected at the February meeting. Both men's and women's styles will be black with tan trim. Cost for the men's jacket is $32, and the women's jacket is $35. Samples will be shown at the January meeting.
Beginners Lecture Speakers Needed
Have you ever considered giving the Beginner's lecture? It's not as hard as you might think. The club is always looking for someone who is willing to share the benefit of their experience. And, if you can't come up with a topic, Ray has a number of topics, which would greatly benefit those who are new to astronomy, as well as the seasoned astronomer. This gives you a chance to learn something new, as well as help others. So, step up to the spotlight! Give Ray a call at 294-1197, or e-mail at raywallace@altavista.com.
Newsletter Cover Photos Needed
Perhaps you've noticed that every month, the cover of the newsletter prominently displays a photograph either documenting a club activity, or which ties in with the main lecture for the month. We have our usual contributors, and a few new ones. Thanks to them for their contributions! But, sometimes no one has an appropriate photo and we have to scramble. I would like to build a library of photos, which could be used in our newsletter whenever we needed a specific subject. If you would like to contribute, please send your photo to the newsletter editor. Be sure to include your name, so we can credit you, as well as details on how you obtained the photograph.
WEBSITES: TRIPS ON THE INTERNET SUPER-SKYWAY
By Rik Hill
Linear astronomy
It's been a while since we had a comet you could see with the naked eye. Our last two, only a year apart as spectacular naked eye apparitions, were Hyakutake (), and Hale-Bopp (). But for the next couple weeks we will have one, Linear WM1. It is presently just naked eye bright and brightening and heading south rapidly. By Christmas Day it will be so far south (about 10 deg. due south of Fomalhaut) as to only be visible from a mountaintop, like Mt. Lemmon. This one will not become as spectacular but still is visible and worth a look every few nights. But in order to find it you will need a good ephemeris. You can find one at the IAU Comet page:
http://pluto.harvard.edu/iau/Ephemerides/Comets/
The specific page for Linear WM1 is at:
http://pluto.harvard.edu/iau/Ephemerides/Comets/2000WM1.html
with a daily ephemeris for Linear at:
http://pluto.harvard.edu/iau/Ephemerides/Comets/2000WM1_1.html
For more information on the comet you can start with the Sky & Tel. comet page:
http://www.skypub.com/sights/comets/comets.shtml
There are good detailed orbital plots at:
http://www.aerith.net/comet/catalog/2000WM1/2000WM1.html
with good recent photos and charts at:
http://encke.jpl.nasa.gov/index.html
The last time I looked this comet was just barely naked eye. Images are being posted on a number of websites. Among the best are:
Chris Schur's page
http://www.psiaz.com/schur/astro/latest24.html
Gary Kronk's page
http://cometography.com/index.html
Now it's your turn. Take photos, make drawings or just go and gawk, but get out there and enjoy this comet before it dives below the southern horizon.
As always, if you know of a particularly good website you would like mentioned here, drop me a line at rhill@lpl.arizona.edu
Steward Observatory Public Evening Lecture
Since 1924 Steward Observatory has hosted public evening lectures in astronomy. Dr. Hans-Walter Rix will present this semester's first lecture on Monday, January 14th at 7:30pm. At this time the title of the lecture is not known. The Steward Public Evening Lectures are held twice a month in the Steward Lecture Hall (N210), the same room we hold our meetings. Following each lecture, the 21-inch telescope will be available for viewing the night sky (weather permitting). The lectures and the use of the telescope are free of charge and open to the general public. Go to http://viking.as.arizona.edu/~taf/pubeve/pub_lect.html for additional information. The complete schedule should be posted in the near future.
Smokers and Sparklers
By: Sharon Koerber, Skyworks
For the 4th year in a row, Steve and I stood in the Sabino Canyon parking lot looking at the Santa Catalina's and sighed. The clouds had already started to cover Tucson. There would be no meteor shower tonight. Every year it was the same thing. Clouds...no meteors. Gloomily we continued to unload our truck anyway. We promised our customers and friends that we would be in the southeast corner of the parking lot at 11p.m. on Saturday night and that we would stay there all night, no matter what.
Aside from the usual sleeping bags and lounge chairs, this year we decided to bring snacks and beverages for everyone who showed up. (Yes, a lot of it was left over from the book signing we had held a few weeks before.) We felt that our luck had to change sometime so making a food offering should do the trick.
Preparations had begun in early October when we sent out postcards, made calls to customers and friends, called the television stations to let them know where Sky Works would be on Saturday night, November 17. We wanted company. Meteor showers are a group thing!
The Helm's brought more equipment for the party, then the Hulderman's with 7 quarts of chili, bowls, crackers and spoons. A real party was materializing. Then another group plopped their sleeping bags and chairs down. By 11:30p.m. two rows of chairs stretched 100 feet from south at the snack table toward the north. We faced the northeast for the best view. Friends in trucks pulled in and chinked the cracks between our rows of vehicles. They parked with their truck beds facing northeast as well, forming a third row. Of course, we got the giggles, for the 4th year. This time though there was more laughter than in years past. What a wonderful sound to fill the darkness on a crisp fall evening!
Present were, Kay Vandermark, Janet and Steve Hulderman, Trish, Roger and Tiffany Helms, Bill and Susan Reddicker, Lancy Matheson, Paula Price, Julie Mason, The MacIntyre's, Larry Scott, the Soule's, John Sosville, John Sosville's son, Michael, Doug Nelson, Terry Little, Nigel Kilduff from Coronado Instruments, with Amy, Holly and John Hosking, Alex (our vehicle rental agent) and his wife, Terry Simo and family, Bill Morris, and more friends we were never able to identify in the dark, we're sorry. Neither do we know the TAAA members from non-members. Since Sunday morning we have received hundreds of calls from friends, strangers telling us they couldn't find us in the parking lot but wanted us to know that they appreciated the invitation to our annual event.
About midnight someone at the north end of the line said "OOOH", as the first long tail meteor shot across the sky from Orion. All of us scurried back to our chairs and snuggled down to watch what little show there was to be seen. Then about a minute later we heard another hoot from somewhere behind us. Then another "aah" from the southernmost person in our group, Terry Little (our newest customer and friend). Then it quieted down again. People started moving around once more.
This year we discovered that the bathrooms were gone. I mean not there anymore. Blank space where once was concrete and flushing apparatus. At first, in the dark, no one could find any facilities at all. Panic set in! Yes, even the men! Every time someone scurried into a thicket of bushes, someone else would be coming out. Then someone spotted a bank of port-o-potties in the tram loop. We were saved! Life was good.
As the evening progressed, the incidence of meteors increased and the clouds dissipated but not enough to get us back to our chairs. We milled around, someone spilled chocolate on Kay's sleeping bag. We made jokes about the chili, the toilets, the lukewarm coffee, the "borrowed" pool chair from a local motel (it was returned safely), the lounge chair brought to the "party" in a Mitsubishi convertible and 1001 uses for duct tape.
Between midnight and 2:30a.m. the headlights of multiple vehicles streaming into the parking lot blinded us. In years past, at peak there were only 50 or so vehicles in the lot. By about 1:45a.m.the parking lot was about half full. By the peak it was 3/4th full. It was unbelievable. Then there was another potty problem. Lines. Life was almost good!
Then the time was 2:50a.m. Someone hooted again to the north. Then again and again as the meteors began streaming into the atmosphere. Pop, pop, pop! Flash, flash, flash! Long and short and north and south and east and west they came. Long tails and flashing dots, double tails and tails that hung in the air for almost a minute. Some with no tails at all. Colors of gold, green, red and blue. Smokers and sparklers! We counted and counted and counted. We started by saying "ooooooh" and then when they came so fast, we were only able to say "o", "o". We laughed and giggled and clapped our hands and cheered! At peak, the count was somewhere between 1800 and 2500 per hour.
By 5a.m. we started packing up. But we lingered, this time in a fully upright position, not wanting to miss the last of them. Finally, it was over. We won't see this again for two-thirds of a century. But that's ok. We watched what a little speck of sky debris can do on Sunday morning, November 18, 2001.
Chaco Canyon Volunteer Opportunity
By: Andrew Cooper
The National Park Service has an opportunity for an astronomer volunteer to provide public viewing and astronomy related presentations to visitors at Chaco Culture National Historic Park, New Mexico. They need someone with experience interacting with the public. For a couple hours of work each day you get the use of the astronomy facility, including a C-14 on an Astrophysics mount, a CCD camera, and a 20" obsession. They need someone who can commit to six weeks or more to enable that person to develop programs and learn the equipment.
For full details see http://www.63.134.241.238/chacovolunteer.pdf or contact Andrew.

TAAA Star Party at TIMPA
January 5 (Saturday)
Come out and enjoy the winter skies! What makes this event special is that our novice members can get help with observing issues or equipment problems. There will be experienced members present who would be more than happy to help. If you don't own a telescope, don't worry. There will be lots of scopes set up and everyone is invited to look through them. This is a great way to check out the different telescope designs before you make that all-important decision to buy. There is no scheduled talk for this activity. Just come out with lots of questions and we'll do our best to get you the answers you need. If you have friends who might be interest in amateur astronomy, bring them along. Be prepared for cold weather and dress warmly. Directions to the TIMPA site are located on the outside flap of this newsletter.
TAAA Star Party at Las Cienegas (Empire Ranch)
January 12 (Saturday)
Las Cienegas (formerly Empire Ranch) has been our normal dark-sky observing site for quite a number of years. Las Cienegas is about 4000 feet in elevation, so be prepared for cold temperatures, and try to arrive before sunset. Stay as long as you like, but let everyone know when you are ready to leave; someone may be taking astrophotos. Bring a telescope if you have one, but you don't need one to attend. Any member would be glad to let you look through their telescope. There are no restroom facilities at the site, so be prepared. Attendees should park their vehicles either perpendicular to the airstrip facing toward the center of the strip or parallel to the airstrip along either side facing west. That way, when you are ready to leave, you will not have to back up and turn on your bright white backup lights. One nice advantage to belonging to the TAAA is the opportunity to observe among friends. Help in finding an object or the sharing of equipment always goes on at our star parties. If you haven't attended a star party yet, you're missing the best part of belonging to the TAAA. See the directions to Las Cienegas on the outside flap of this newsletter.
