              ------------- ACTIVITY LOG --------------
Observing Specialist: N.Ule
Light cloud cover made early observing difficult (target was faint), sky
was fine after 22:00.
Second observer complained of an unusual pattern on Spicam.  Observer was
concerned and so I promised to include what we saw in the night log.  After
an hour of observing we took flats in the i and r fliters.  Both showed the
same pattern, which was vaugely mushroom shaped.  Observer commented that
he had not seen anything like this the last time he observed with spicam.
 Flat fielding should take care of this, but I am unaware of any strange
patterns on the CCD.
