MDM Trouble Report for 2003 Feb 23

Telescope: 2.4m
Observer(s): pizagno (OSU)
Instrument: CCDS

Problem(s) Encountered:
At the end of the night  blotches ,  veins , and 
 streams  suddenly appeared in the images.  They 
were seen in the data frames and flat frames.  
It appears like a drop fell on the camera optics, 
but I am not sure.
