Mid Shift Summary

H1 had a lockloss after a 2hr lock.  

During acquisition noticed a rough alignment, and so locked PRMI to check alignment.  When bringing SRM back, it would saturate and its watchdog would trip.  SRM appears to be in an odd state now (see Evan's alog).  We toggled power on the SRM driver box in the CER (not sure if this did anything though).  Evan & Stefan then took control and carefully checked alignment & ASC.

Oh, and another issue is we've had to "FIND_IR" by hand for last few lock attempts.

This is where we are now.  Looks like L1 is up to Observation Mode.

2:29UTC there was a GRB.  We were out of lock.  Talked to Joe at LLO and they were locked.  They did receive the alarm.  They were in the middle of PEM injections however.

Environmentally:  the winds have picked up to around 20mph.  Most other seismc channels look fairly quiet.
