Ops EVE Shift End

TITLE: 01/16 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 147Mpc
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY: The rest of relocking today from when I arrived went smoothly, and we have been Observing since then and have now been Locked for 7.5 hours. The range is still super glitchy and throughout my shift it felt like the DARM FOM was constantly jumping.

I wasn't able to find any reasons for why we've been so glitchy these past few days, but I did notice that hveto had found some auxiliary channels and had used them to veto quite a few triggers (Jan14, Jan15). Namely, on Jan14th H1:CAL-PCALY_RX_PD_OUT_DQ, on Jan15th H1:SUS-ETMY_L3_OPLEV_SUM_OUT_DQ, and on both days H1:PEM-EX_VMON_ETMX_ESDPOWER48_DQ. Tagging detchar
