Problems: 

- 08:26 Fails to START exposure on T0142378043, rebooted OPTGUI 4 times.  Skimmed through logs in /mir7/logs/IOS/2021/02/01/ 'maybe' the most repeated error is "ERROR 111 writing_message positioning slicer motor to slicer position ..." e.g. log 210201052431_ios.log

Comments: 

- Closed at 00:05 UT,  high relative humidity (79% and going up.) Open, 01:55 UT

-02:02  OPTGUI START fails to start on T0175532955, rebooted OPTGUI, ok.
- DIMM seeing monitor started ~ 04:15 UT
- Reminder: A/C unit is not working fine (if not controlled, T reaches 35C.)
- No time for T0429295277; completed the last integration on G2K001325 (1st the brighter, then fainter at SW: not clear 2 me what is the object! expmeter did not stop integration at given limit) with the Sun at -9.3 degrees of altitude.
