Comments: 

Cloudy and poor seeing :-(. 

Program incomplete, 4 targets skipped due to clouds (TIC0094011343,  RKS1149-2020, TIC357312511, RKS2004-1601).

A212954 observed through clouds. I increased the exposure time to 1800s, but I had to stop it before because I lost the guiding star. I gave it another try at 9:42UT but the clouds were too thick.

V907 Sco second observation also observed through clouds, increased exposure time to 900s.
