QUICK SUMMARY:
IFO is in NLN and OBSERVING (3 hr 35 min lock)
- When I got in, the H1 CS Dust LAB1 300NM Dust Alarm was sounding, so will investigate this.
- Per a sticky note left on the screen hinting to alog 78729, I put SUS_ITMY L3 Bias back into SDF Monitoroing. While TJ's screenshot hinted at 4 SDF Diffs (3 in ITMY and 1 in ITMX) to remonitor, I only found the 3 diffs for ITMY and re-monitored those (screenshot).

Optics Lab (Lab 1) Dust Cts have settled since an excursion about 1 hour and 10 mins ago which saw elevated levels for 11 minutes at around 13:34 UTC (6:34 PT). They triggered the yellow alert, and almost got up to the red alert threshold but did not quite make it. Counts came back below threshold at around 13:45 UTC. Trend screenshot attached.
