Problems:

08:12 UT G2K000299 did not start integration, ThAr and motor still ON.

Comments:

Increasing like cirrus clouds moving from N and E since ~ 1 UT. No DIMM: 01:57 to 04:05 UT
(clouds mainly due E, N; N winds ~ 15MPH.)
G2K002171 Telescope moved W, added 25 [s] to compensate.
GAI2105-2928_gap Tel moved W, added 50 [s] to compensate.
G2K000020 looks like a very low, noisy S/N
Second try on G2K000027, guiding with the faint companion: better than 1st try!
Program + some extras completed with the Sun at -11.9 degrees of altitude.
