STATE of H1: Observing at 136Mpc
INCOMING OPERATOR: TJ
SHIFT SUMMARY: Standing down for high winds on site for the first half of the shift. Able to relock once wind was quieter and have been observing since. Winds are still high so things are less stable and range is lower.
- Started shift pausing at ADS_TO_CAMERAS (before SQZ) for SQZ team to run some tests
- 23:18 Reached NLN
- 23:50 Lockloss - alog
Tried relocking three times, but could not get past locking ALS due to the (now much higher) wind gusts. Jenne made the call to stand down until the winds died down (alog 72536).

- 03:13 Lockloss from DRMI_LOCKED_CHECK_ASC
- Fully automated acquisition
