TITLE: 04/05 Eve Shift 23:00 – 07:00 (16:00 -00:00), all times posted in UTC

STATE of H1: Observing at 110 Mpc

INCOMING OPERATOR: Patrick

SHIFT SUMMARY: Had a few hours of Observing at the beginning of the shift. High wind/microseism knocked us out of lock and prevented the IFO from re-locking for a while. Tried MORE_WINDY and VERY_WINDY_NOBRSXY seismic configurations with not much luck (probably due to the microseisms). It finally down enough to let us relock at 04:45. Leaving the IFO in Observing for ~2 hours. Total Observing time during the shift is a little under 5 hours.
