H1 Back to Observing

(Driggers, Gray, Kawabe)

Whew!  What a day!  Started off the shift with Maintenance still going, but then moved immediately into running an alignment.

The alignment was OK, but the FSS started oscillating during it.  It took a good 20min to get it back.  After the alignment, made it to DRMI and the flashes/alignment looked good, but basically for the next 4hrs, could not get it to lock (See Jenne's alog). 

The FSS has been causing downtime during this shift for any time the IMC breaks lock.  Sometimes it comes back within a few minutes, but there have been other times when it's taken over 15min.  (maybe it's due to the SDF changes listed below?)

Eventually got H1 to Observing at 6:34!

There were SDF diffs (ATTACHED) for:

GRD_IFO was in the Automatic Operation.  So as soon as the SDFs were cleared, Intent Bit went to OBSERVE on its own.  (I switched it back to MANAGED)
