Institution(s): Columbia

Instrument: Modspec

Worked for 9 hours (all night)

Observing Summary:

At the beginning of the night the pointing was off by about
1/4 degree to the east.  We had to use the tilt meters to correct
it.  (It is always north by about 1 arcminute too).

The seeing continues to be bad.  Although it was photometric
tonight, it seems that we are headed for worse weather.
