Subject: [AstronomyOutreach] Countdown to 500 Comets: no 412 Sent: Saturday, October 6, 2007 12:02:49 From: Alan Hale (email@example.com) Comet LONEOS C/2007 F1 Finally -- it looks like we have a "Countdown" comet that could become relatively bright. It is currently running 1 1/2 to 2 magnitudes brighter than originally expected, and if it maintains this trend it could reach a peak brightness between 3rd and 4th magnitude when near perihelion in late October. Although currently a morning comet, it will be conveniently located in the evening sky when brightest, although at a fairly small elongation (20 degrees). The comet emerged from conjunction with the sun during the latter half of September, and for my first observation I had to travel about an hour's drive away to find a perfectly flat horizon in the right direction. On September 22.48, m1=9.7, 2.2' coma. As with the previous comet, I'm posting this late because of the motherboard failure of the computer with which I maintain the "Countdown" web pages. Fortunately, the comet is now higher in the sky (and brighter) and I don't have to make the long drive anymore. Description at http://www.earthriseinstitute.org/coms41.html#412 This comet should present an excellent opportunity for general public and student comet observing. Images and reports (including reports of outreach efforts) are welcome. Sincerely, Alan
