OPS Day Midshift Update

Ryan C taking over for the last 4 hours but here's what happened in the first 4:

After issues getting the IMC locked during SRC_ALIGN, we manged to automatically get to NLN, Observing at 16:04 UTC.

SQZ Tuning: Dropped out of OBSERVING 17:14-17:26 UTC

Calibration Sweep: Dropped out of OBSERVING 18:34 UTC - Lockloss 19:05 UTC

Lockloss (alog 80760): FSS Caused lockloss during simulines.

Timing glitch followup (Dave):  While yesterday's EY time glitch had no consequences. Dave said that it has been glitching by quite erratic numbers lately and has recommended another power supply swap (like the EX one recently).

Fast Shutter Guardian Glitch Followup: Dave found that the guardian fast shutter malfunction yesterday was caused because there was a 5s delay in data-grabbing but why that happened is unknown. He will post an alog about this soon.
