STATE of H1: Observing
SHIFT SUMMARY: Just got back to NLN from a lock loss. Recovery today has been mostly hands off. The lock losses today are still unknown and need more people to keep looking at them.
- Lost lock at 1635 - lock loss 1370190932
- Reacquired fully automated
- Observing 1749 UTC
- Lost lock at 2107 UTC - 1370207267
- Reacquiring DRMI wouldn't catch even though it had what looked like good flashes. The camera showed some yaw misalignment, even after PRMI was run. It lost lock, and then after it came back to this point it eventually caught after running another PRMI. I was impatient and tried to move SRM before PRMI ran this time, but made it worse and reverted. These two lock attempts were slowed down by ALS. It wouldn't catch on either arm, despite decent flashes, so increase flashes was run for both arms. We might need to look into speeding this up.
- Observing 2303 UTC
