Come celebrate the solstice with your astronomy club, on December 20, the third Friday of the month. TVS will provide delicious roast turkey and baked ham, cooked to perfection by club chefs Rich and Barbara Green. By popular request, this year's "assignments" have been changed! Please see the list below for your contribution to the potluck. The first letter of your last name determines the dish you should bring. Please prepare enough to feed eight to ten hungry astronomers.
|A through G||Dessert|
|H through R||Vegetable or Salad|
|S through Z||Rice or Potatoes or Dinner Rolls and Butter/Spread|
After dinner we'll swap observing tips and pass along good ideas for stocking-stuffer gadgets.
Others elected or re-elected to board positions are: Alane Alchorn, Dennis Beckley, Rich Combs, Russ Kirk, Dave Rodrigues, Debbie Scherrer, Al Smith, Dave Sworin, and Jim Zumstein. Rich Green continues in his ex-oficio position as past-president.
These new and familiar faces can be seen monthly at a new time. The General Meeting night now moves to the third Friday of each month. Dates for 1997 are: January 17, February 21, March 21, April 18, May 16, June 20, July 18, August 15, September 19, October 17, November 21, December 19.
The membership/renewal application form on page 6 has been reformatted to include a hold-harmless statement and electronic options for those of us with Web and cyberspace connections. If you wish to be notified by e-mail when the newsletter becomes available on the Website each month, please put an "X" on the appropriate line on page 6. Likewise, mark the corresponding line if you do not wish to receive Prime Focus by mail any longer.
Discounted subscriptions to Astronomy , and Sky & Telescope . are available at $20 and $27 respectively. Please mark these lines if you want to be included in the club order. It will be submitted the Monday following February 's general meeting. Subscription fees should be added to your annual dues on a single check, payable to Tri-Valley Stargazers.
Patron membership is available after one year of general membership in good standing, subject to the approval of the board of directors. Patrons pay an additional $40 annually, over and above their general dues. They have access to the 17.5-inch telescope and the Sky Shack observatory. Patron membership is limited, with first priority given to active Patrons wishing to renew. For details, call vice-president Chuck Grant at (510) 449-1500 (yes, this really is his home number).
If your employer provides matching funds for charitable donations, the club benefits twice from your donation, no matter how modest it is. A line for TVS contributions has been provided on the revamped application form on the last page.
You, and your employer if applicable, will receive an acknowledgment of the donation, suitable for proving to the IRS that you are all-around good guys and deserve a tax break accordingly.
The board is looking for a Speakers and Programs committee chair. This individual will assist in selecting the program topics for general meetings, and in scheduling and confirming speakers on those topics. Coordination with the board can be accomplished by e-mail and phone, if it is a burden to attend planning meetings.
Even nearer to our hearts (and stomachs) is the Hostitality chair. He or she arranges for beverages and snacks at each general meeting. The club foots the bill for these edibles, but needs someone to fetch them.

Comet Hale-Bopp continues to brighten as it passes north of the Sun and into the morning sky as 1996 draws to a close. Northern hemisphere observers will have difficulty seeing it for a few weeks, while southern hemisphere observers won't see it until May 1997. While Comet Hale-Bopp has developed jets near the nucleus, and a tail a few degrees long. Comet Tabur began to fade rapidly in late October. This was unexpected and it is unusual behavior for a comet. It may now be fainter than the adjusted magnitude estimates listed in the ephemerides below.
Several comets should be easily visible to us in 1997. Comet Hale-Bopp will likely be the brightest, reaching perihelion in late March. Between January and June, Periodic Comet Wild 2 will reach magnitude ten in the northern evening sky. At nearly the same time Periodic Comet Wirtanen will be of similar brightness. Periodic Comet Encke is visible to the southern hemisphere in mid-summer. Toward the end of the year Periodic Comet Hartley 2 may reach binocular visibility in the evening sky, while Periodic Comet Tempel-Tuttle crosses through the north polar region at magnitude nine. In addition to these returning periodic comets, one never knows when and where new comets will be discovered.
