STATE of H1: Not Locked
OUTGOING OPERATOR: Cheryl
CURRENT ENVIRONMENT:
SEI_CONF state: WINDY
Wind: -
Primary useism: -
Secondary useism: -
Summary:
H1 just had a lockloss, which looks like it was due to a High Voltage trip at HAM6 (which trips due to Vacuum pressure at HAM6). Several people have been investigating & trying to restore via instructions from Richard, but have not been able to untrip the HAM6 Hight Voltage. Richard M is now driving out.
This lockloss was at 22:59 UTC & since its fairly confirmed to be due to a hardware issue, we should be marked DOWN for CORRECTIVE MAINTENANCE from that time (vs about 0:25 when we took OBSERVATORY MODE to that state).
