Comments: 

- 00:40 UT cloudy, waiting. Improved greatly after 01:40 UT.
- 04:30 UT clouds are back, unfortunately. Impact on TOI-1985 (files 1151 and 1152.) Telescope drifts W, bad guiding affects in particular file 1152.
- 5 UT Telescope DOWN at the OPTGUI which also fails to start integration, rebooted OPTGUI, ok (noted TCS felt slow.) Too cloudy on G2K001162/3, skipped.
- File 1154, displays a diagonal up-down, left-to-right: a strong cosmic ray?
- 04:30 UT - 07:00 UT unstable lectures from DIMM seeing monitor.
- No time to observe: G2K001162/3, T0411614400 and T0217933560.
- Last quarter of night evolved from thin clouds to completely clear.
- Last integration completed with the Sun at -10.3 degrees of altitude.
