2011 April 24:

Xiao filled the dewar before FB arrived, and pressure seems high (3e-6). After refilling both dewars, the pressure went down to 6e-7.

Did the alignment on beams 4, 5, 6 so as not to impede on CLIMB run (+ we need to measure the fringe position again now that the IR5 repeatability problem has been cleared).

All computers had to be rebooted due to a long power outage this night, including lothlorien, wolverine, zoot. Had to restart all servers (shutters, etc.).
