STATE of H1: Lock Acquisition
INCOMING OPERATOR: TJ
SHIFT SUMMARY:
A few earthquakes rumbled through, but we made it through them OK. H1's range is looking decent as it is just under 120Mpc...it's been a bit glitchy the last 5hrs though.
Operator Note: Calibration Pipeline still needs to be restarted (I"m assuming when H1 is not locked....Aaron & Maddy were sleeping during the lockloss during my shift).
