Mid Shift Status
H1 continues to have a rough day with short locks, and it's gotten worse with H1 dropping out at various states while trying to get to NLN. Although H1, had been locking DRMI sort of decently, ran an Initial Alignment to see if this can help (it had been over 24hrs since the last IA was run).
For the last lock about 3hrs ago, OPO temperature was adjusted and this yielded a better range, but it was only locked 47min.
Locking woes continue. Have had a couple of locks make it all the way past MAX POWER only to have locklosses, but most of our locklosses of late are early ISC LOCK stages. This is some weather. Winds are now in the 30mph range and microseism is above 50th percentile.
