TITLE: 02/21 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 68Mpc
INCOMING OPERATOR: Travis
SHIFT SUMMARY:

Other than a big South American EQ which took H1 & L1 down, had a nice shift.
LOG:

• 11:00 EQ
• 12:16 EQ
• 14:30 LOCKLOSS, 6.5 Bolivian EQ
  • Took OBSERVATORY MODE immediately to LOCKACUISITION, but eventually went to the more apt EARTHQUAKE state.
  • Went to LARGE_EQ_NOBRSXY briefly & then back to WINDY
  • After swinging around a little proceeded with locking.
  • 15:17 OBSERVING, even though we are 43min away to MAINTENANCE DAY...no one is lined up for Maintenance, so padding our UP-Time! 
• CS ECAT PLC2 SDF Diffs AGAIN!
  • Similarly to Nutsinee, had an SDF Diff.  H1:IMC-REFL_SERVO_IN1GAIN has been drifting from -8 -> -6 -> -7(currently).  I ACCEPTED this Diff; snapshot attached.
• ~15:37 Bartlett gently driving his truck to OSB Receiving
  • Huge glitch appeared on Range...wonder if this is due to his truck approaching.
• 15:42 Bartlett opening OSB Receiving Roll-Up Door--->No Glitch
• 15:47 Bartlett driving his truck away--->No Glitch
  • This probably means the 15:37 glitch was something else.
• 16:00 MAINTENANCE DAY BEGINS
