              ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Few clouds at sunset. Clear at midnight. Elevated dust levels.
Echelle slitviewer images looked like a flat field but only on some fields (see fits
files around 100-110). There were no error messages. I restarted the software to see
if that would help. Not sure if we had the right field to begin with, star looked
too faint. Brighter stars did not look like they were washed out, so maybe the
contrast for faint stars is problematic.
No other problems.
