Around 2:45AM clouds started to appear low in the S/SW. I found a bug in TUI that I was using (PR submitted) that didn't allow it to abort/stop exposures. With more clouds looming on the horizon, and not being able to identify the next field (due to clouds), plus the TUI bug, and 4x900s exposures for the targets, I opted to stop observations until the weather improved. The clouds just got thicker and by 5AM we had some light sprinkles falling. I gave up at this point. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- UW15 E I/S 00:15 00:15 TUI Ctrl+clicks started moving the star in the opposite direction than expected.
