4:11  Had a random lockloss.  It's windy out, but not too bad. 

As were were seconds from getting to NLN, we had a GRB (Swift) & this was confirmed with Will at LLO. 

Also had another H1SYSECATC1PLC2SDF diff similar to yesterday.  It is related to the Refl Servo Gain, and this time we were at 6dB (vs 7dB which was ACCEPTED by me yesterday).  This matches what Thomas wanted from his alog yesterday.  So, perhaps Guardian now accounts for this & we should be good for future locks.

4:51 OBSERVING.
