OPS Friday OWL report

Statues of H1: Relocking at CHECK_VIOLINS

11:04UTC H1 called for assistance as the NLN timer had expired with IA already been run. We were at PREP_ASC_FOR_FULL__IFO and I can see that the Violins look huge on DARM, H1 lost lock at MAX_POWER twice this morning/night so that's probably why (tagging SUS), most of the other LLs have been at ALS, presumably these ALS difficulties are from the increased ground motion. I'm going to have to spend some time damping violins it seems.

After spending about an hour in OMC_WHITENING damping violins and increasing gains we've reaquired NLN at 13:04UTC, back into Observing at 13:04UTC
