We are scientists studying Comet ISON and members of NASA's Comet ISON Observing Campaign team. AMA!
Comet ISON is blazing towards a close approach with the Sun on Thursday (November 28). It has captured much popular and scientific attention due to its brightness, unique orbit, and spectacular appearance. It has already been studied by an unprecedented array of ground- and space-based telescopes, and even more incredible images should be acquired by solar telescopes over the next few days. Stay up to date on the latest news about Comet ISON at http://www.isoncampaign.org/
Answering questions today are -Matthew Knight (Lowell Observatory) -Karl Battams (Naval Research Laboratory) -Elizabeth Warner (University of Maryland) -Padma Yanamandra-Fisher (Space Sciences Institute) -Ron Vervack (Johns Hopkins University-Applied Physics Laboratory. They are all planetary scientists studying Comet ISON and member's of NASA's Comet ISON Observing Campaign team. They are happy to answer questions about Comet ISON, sungrazing comets, comets in general, and solar spacecraft observing.
Update: Since we're new at this, we just wanted to say that we'll be starting at 9:00 PM EST and plan to go for an hour. We're all logged in together, but will answer individual questions with our initials.
UPDATE #2 We're having fun doing this so some of us will keep answering questions until our hands cramp up too much. Thanks for all the interest and keep posting questions! (MK)
UPDATE #3 I think we've just about answered all the questions. Thanks to everyone for participating, and here's hoping that ISON performs for us! (MK)
