TITLE: 03/11 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 155Mpc
INCOMING OPERATOR: Oli
SHIFT SUMMARY: List of maintenance activities below, the most impactful to locking being the camera server change that we ended up having to revert to resume locking (alog83308). We will try to implement these cameras that are used in locking a different day when we can dedicate time to setting the IFO to their new offsets.

We had a cold cathode gauge trip during yesterday's maintenance period, H0:VAC-EX_X2_PT524B_PRESS_TORR is the channel from the signal for the cold cathode gauge. The gauge pair, cold cathode and the pirani gauges, are located next to the gate valve number 20 (GV20), not far from the P-Cal transmitter pier. These gauges are very sensitive to interference from communication devices, such as two way radios and mobile phones, please try to keep communication devices away from all vacuum gauges, thank you.
Now, we wait for the gauge to comeback on its own.
