H1 General (Lockloss)
camilla.compton@LIGO.ORG - posted 14:43, Tuesday 13 June 2023 (70424)
Tuesday Maintance Lockloss 15:08UTC and Relocking back to NLN

Caused a deliberate Lost lock for Tuesday Maintenance at 15:08UTC (1370704124) alog70399

Relocking was uneventful. Prior to starting initial alignment (while other work was finishing up) I manually touched ETMs and TMSs for better green flashes and then completed an initial alignment.

The lock acquisition itself was completely automatic but we did loose lock twice (TUN_ON_BS_STAGE2 and OFFLOAD_DRMI_ASC). I expect this was due wind > 20mph, plot attached.

NLN at 21:14UTC, Observing at 21:25UTC.  Brina accepted a sdf for alog70423: 4:1 Hz MICH1 FM3 filter.
