Problems:
Finished calibrations 8pm due to DECam server issues.
GCS Failure on first exposure.
Guider Alert on exposure 193864. Message: Continous null centroids exceeded.
Guider Alert on eposure 193866. Paused mid exposure. Message: No active CCDS. Increased guider exptime to 1200mn. No further guider failures in u band after this change.
Image Health tool crashed early in the night.
Lost connection to Observer Console. Refresh solved issue. (Oddly enough this fixed the problem with the exposure time not correctly displaying the time remaining with the filled bar)

Explaination of the RASICAM plots in Telemetry Viewer would be nice.
Pointings driffted by ~25 arcseconds in RA and DEC for each of the 2 pointings over the night. Pointings were dithered over 4 hours over ~0.5 degrees.
Finished u band exposures at 5:30.
Changing guider exposure time mid exposure seems to have no ill effects. Applies the updated exptime to next exposure.
