Problems:
- 00:36 UT Fail to START integration on T0119292328, rebooted OPTGUI, ok. Found in /mir7 logs file 210301213547_ios.log, 3 "ERRORs 111 writing message": setting detector speed..., positioning slicer..., setting geometry mode. Either the slicer was stuck or the system did not set the geometry (binning.)

- 02:02 UT ThAr file 1134 looks like a bias, renamed as JUNK.
- HD 101259 NOS coordinates wrong? Nothing there, used CDS coords RA::11:39:00.442 DEC::-24:43:15.94.
- At 03:50 UT MML 48 is still beyond telescope limits. Once at 4 hours HA still fails (unstable balance, telescope FALLS East.) Waiting! Finally started at 05:09 but telescope drifts E even though HA is by now < 3hrs 40 mi. Guiding manually. There is a "periodical" ~5 seconds jump or slip in RA that moves the telescope ~10 arcseconds E. Once HA< 3hours and using shorter integration times, guiding improved to auto.
- After 5 UT, a few thin clouds from S, SW. Around 7 UT thicker clouds moving W to E, impact on files 1158, 1159 and 1160. By the time of 1161 and later was clear.
- Completed last integration with the Sun at -8.4 degrees of altitude.
