For your perusal...
Sarah Garner's Page O' Announcements:
Sarah Garner (front office) receives lots of emails about various events and opportunities, too many to forward them all to us, in fact. In order to make them available, she puts them all on a webpage. Also includes the class schedule for the next few quarters (very handy). Certainly worth a regular look.
Department Wiki:
This link takes you to the astronomy department wiki. Specifically the undergraduate section. Here you will find lots of information for new and experienced students alike. The wiki is a treasure trove that spans almost every aspect of astronomy work here at the UW. Enjoy.
