STATE of H1: Observing at 142Mpc
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY: Currently Observing and have been Locked for 4.5 hours. We were aiming to stay locked during today's maintenance period, we did lose lock but it was just from turning the BRS for the end stations off. Relocking took a while because of maintenance going on but there wasn't much intervention needed and we were back locked much earlier than we would have been if
