Current schedule is for first 7 TeV center of mass collisions tomorrow (Tuesday) at 9:17 am Geneva time. Injection of the beams will take place after 2 am, ramp up to 3.5 TeV/beam from 3-4 am. For more details of what has been going on recently at the LHC, see here. The schedule for tomorrow is here, a link to the planned webcast is here.
Update: I just woke up, a couple minutes after first collisions were observed, 12:57 Geneva time. Collisions are going on now.
