Messier Marathon 2007

The 2007 Messier Marathon will perhaps be one of the last occasions to combine a nine-planet marathon with the Messier event, but Neptune will be extremely difficult if at all possible, Uranus also difficult in the morning. Some comets brighter than about mag 14.5 may be visible; we will list them below from various sources (e.g., IAU's Observable Comets page, Gary Kronk's list of current comets and the Fachgruppe Kometen list):

Comet                         RA  (2000.0)  Dec  mag  
                                  March 16, 2007

C/2006 L2 (McNaught)          21:40.65 +68:09.6  14.9

C/2006 P1 (McNaught)          22:55.36 -66:14.9   9.1
96P/Machholz                  23:36.88 -25:16.6  11.8

Note that occasionally comets become bright shortly (like Hyakutake in 1996, Ikeya-Zhang and Utsunomiya in 2002), so check back for possible updates shortly before Marathon date.

Also, meteors from various showers may occur, and depending on your location, you may be able to observe the International Space Station, ISS.

• The Old Town Sidewalk Astronomers will escape from the Los Angeles County city sidewalk lights and head to the Colorado Desert for another Messier, planet and comet Marathon Saturday night March 17, 2007. Our location is on +33d 40' 5.02", -115d 32' 51.83" between Chiriaco Summitt and Desert Center, CA, a spot we learned about from Messier Marathon great Don Machholz. You can use the road map on the Desert Center Clear Sky Clock for directions. The road to the right of the railroad tracks is Red Cloud Road. If you plan to join Jane and Mojo, please plan to arrive before sunset, as Red Cloud Road is a washbord dirt road. They usually set up about a mile down the road. If you plan to leave before dawn, they'll ask that you park facing the road, try to turn off all interior car lights, and announce your departure to the group well in advance. It's a huge area, with a couple of miles of flat observing space on both sides of the road. Other astronomers are often setup further down the road, and there is room for everyone. This is not a road for heavy vehicles or RV's. Last time someone brought one, it took hours for Triple A to haul it out of the soft sand. - Jane Houston Jones
• The San Jose Astronomical Association holds annual Messier Marathons. This year is holding a marathon on Friday 3/16 and Saturday 3/17. - Rob Hawley, President SJAA
