SGS Guider Zero-Point Offset (GZPO) setting: X(RA)-102,Y(Dec)30 ___end___ UCoMP COMMENT BY mcotter: Thu Feb 11 21:44:44 GMT 2021 After moving the O1 to best align the O1 to the center of the field lens (X axis on the cameras). A couple data sets of 1083 vs focus data were taken to trace how the image moved (in X) over the course of the focus range. This ended at 20:30UT The instrument plate was then lowered about 2.2mm (2 turns) on all 3 knimatic adjusters to center the sun on the field lens in Y. This is likely the end of the UCoMP hardware work for today. We are now going to take some more focus data in UCoMP and restart kcor observations. ___end___ Thu Feb 11 21:44:51 GMT 2021 Kcor Focus/alignment program exited Thu Feb 11 21:49:14 GMT 2021 KCOR Start Synoptic Patrol Thu Feb 11 21:56:16 GMT 2021 KCOR End Patrol UCoMP COMMENT BY mcotter: Thu Feb 11 21:56:46 GMT 2021 Left a field lens cover in UCoMP pausing to remove it. ___end___ **UCoMP PROBLEM COMMENT BY mcotter** : Thu Feb 11 23:50:12 GMT 2021 UCoMP O1ND filter removed and stored in its box. ___end___ GENERAL COMMENT BY mcotter: Fri Feb 12 03:39:17 GMT 2021 Cleaned and organized tool boxes in observatory and control room.
