Today is the first day of classes for most of the University of California system, and student activists at UC Berkeley are marking the day with their first student protests of 2011-12.

UC generally, and Berkeley in particular, have been a center of American student organizing in the last few years, though administrative crackdowns have quieted the campuses somewhat in the last twelve months. With the summer announcement of new tuition hike proposals that could nearly double UC fees in the next four years, however, things may be due to heat up again.

The organizers of today’s protest announced their agenda in a Daily Cal op-ed earlier this week, and the paper is planning a liveblog of the day’s events. Activists have already started livetweeting the day at the #Day1 hashtag.

I’ll be away from my computer for most of the afternoon (Eastern Time), but I’ll try to update as events warrant, either here or on Twitter. And with UC back in session, I’ll be posting updates on several big stories from the summer in the very near future, so stay tuned.
