TITLE: 08/31 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 158Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: Currently Observing at 158 Mpc and have been Locked for 5 hours. Lockloss was fast and easy to recover from - the IFO just needed my help grabbing ALSY for the same reason we've been seeing for a while: SCAN_ALIGNMENT had taken it to a good-looking spot (above 1), but it wasn't high enough to catch. A few taps was all that was needed.
We had another test of using the ASC Hi Gains button again! During the earthquake, peakmon started creeping up above 500, and picket fence was showing multiple stations were yellow or orange. I tried to hold off on leaving Observing as long as possible since the ground motion wasn't that bad yet, but I eventually started the transition to ASC Hi Gain when I saw peakmon hit 900, but it quickly went above 900 and by the time we started transitioning over, we were above 1200 and quickly increasing. Luckily, we didn't lose lock, but we were close, so I definitely should've transitioned over sooner! This earthquake went up to 2200 on peakmon. Afterwards, the transition back went smoothly.
