              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Seeing vertical streaks on almost all bright stars in slitview images now.    Known shutter issue.  We know how to work around this for guiding.  Just an FYI for our engineers.
dis slit frames 2069 had some odd horizontal banding and contrast issues. Looks like things started in image 2058.
No other problems tonight.
