              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
UW class: G.Eadie, B.Bolin, D.Bektesevic
The noise in the DIS slitviewer camera is really annoying tonight.  Maybe 80% or more of the images have some level of noise, and some were pretty bad/unusable for a lot of the first half. THey were observing very faint (18th mag) objects and we had a fair amount of clouds to deal with. By the second half things seemed better (both sky and camera).  They were also using an ND3 filter in front of the camera too.  They were also observering a very bright target (Jupiter) so that may have helped.
No instrument or telescope problems otherwise.
