              ------------- ACTIVITY LOG --------------
Observing Specialist: N.Ule
Time lost to equipment was due to secondary and tertiary mirrors both had
errors on them, Bill and Russet worked on it, we got the mirrors into
position but the cause of the problem(s) will need further investigation.
Once the mirror problems were corrected observing was fairly routine except
for some pointing problems.  For more information see Russet's email.
Some clouds began to move in around 0215 but did not effect observing.
Don York (UC01) was on in the afternoon and early evening building a
superflat for the Echelle.
