TITLE: 03/21 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC

STATE of H1: Observing at 68Mpc
INCOMING OPERATOR: Jeff
SHIFT SUMMARY: Maintenance day. Tumbleweeds blocked the Xarm so that filtered out some work. I had some issues locking with ALS_DIFF not fining IR and causing a lock loss. 12 seconds after it would set the offset to 1380, the IMC would drop out and kill the lock. What eventually worked, although it did not identify the problem, was going through that step by hand and scanning through the offsets slowly. I'm not sure if it will happen again so future operators be wary.
