December 2010 Gamma

On December 9, 2010, Nicolette Lau tweeted:
 * So much for that comp day. And here I was thinking we were actually going to make it through a major world holiday* undisturbed for once.

The next morning, Chaz Villette tweeted:
 * @madgastronomer You picked a good morning to cheer me up. Just arrived in Houston. Underslept.

Late that night, he posted the following "locked/work" entry to his LiveJournal:
 * Don't know if I can do this, guys.
 * But I know I can't not. So I guess I get to.

The obvious inference is that some sort of gamma hunt took place, starting on December 9, and including Chaz flying to Texas.
