H1 just had a drop from OBSERVING due to the Squeezer's OPO_LR. The Squeezer came back on its own in less than 2-min.
We do have the following message for the SQZ_OPO_LR node:
"pump fiber rej power in ham7 high, nominal 35e-3, align fiber pol on sqzt0"
And it looks like SHG Fiber Rejected Power has had a high value (over 0.350 counts) since Mon (see RyanC's alog83406) and has been railing at 0.753 the last few days. (see attached). Trending back further shows that this Rejected Power hasn't had this sustained railing since way back in Aug-Oct 2023.
Since H1's been (1) running like this the last few days, (2) SQZ came back quick, and the (3) H1 range looks "normal (around 150Mpc)----took H1 back to Observing and tagging SQZ.
