Observing at 02:32 UTC

Locking DRMI took around 35min. It would start to catch it for a second and then lose it. This happened a handful of times before I went to just lock PRMI. PRMI locked very quickly and needed minimal adjustment. Went back to DRMI and it was the same story, and alignment looked good. Eventually it locked and stayed lock.

There was an odd SDF difference before I went back to Observing. H1:LSC-TRIG_MTRX_2_8 was 1.0 but was saved at 0.0. This was the ASAIR_B_RF18 leading to MICH_TRIG. Trending it showed that it has been 0 for the last few days. I didn't see anything in the alog. So I just put it back to 0. Not sure why it would have suddenly changed...
