   Beg: Fog/Low Clouds, Winds Light & Variable, High Humidity 
   Mid: Seeing 1.63 arcsec, Clear, Winds Calm
   End: Seeing 1 arcsec, Patchy Clouds, Winds Calm

Observing Summary:

The beginning of the night we did not open the dome because of
high humidity (snowed last night). We opened at 08:55 after weather 
conditions improved. While observing NGC3227 (UT 09:20, RA 10 23 30
DEC +19 51 54) the target moved within the slit even if the guiding
was properly working. It moved both in the E-W and N-S direction of 
few arcseconds. The spectrum results compromised but we decided to
move to the next target since we have limited time. The rest of the
observations were fine.
