On Dec 16, 2011, the recently discovered comet C/2011 W3 (Lovejoy) became instantly famous. Comet Lovejoy not only survived perihelion but its journey around the Sun was chronicled by a dizzying array of solar and astrophysical missions. There is much to be learned from this and other members of the Kreutz sungrazing family, but the only sure way to maximize the return is to bring different science communities together.
This two-day workshop is for those willing to put in hard work and bring serious, thoughtful discussion to the table. It is imagined that collaborations will be established that will possibly survive until the next surviving sungrazer.
With registration, you will have access to a collaborative wiki site that will be used to share data and ideas prior to and probably during and after the workshop.
Select "Comet Lovejoy Workshop" from the pull down menu.
