MDM Observatory 2.4m Telescope Observer's Report for 2003 May 26

Observer(s): Fesen
Institution(s): Dartmouth

Instrument: Echelle Direct

Worked for 9 hours (all night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 2.0 arcsec, Cirrus, Winds Light & Variable
   Mid: Seeing 1.5 arcsec, Cirrus, Winds Light & Variable
   End: Seeing 1.0 arcsec, Cirrus, Winds Calm

Observing Summary:

Some light cirrus but mostly clear. Seeing was highly variable
ranging from 0.9 to > 3 arcsec. Nonetheless, obtained
excellent data. However, while looking 3 hrs over to the east,
the E-W tracking failed in the same manner as 4 and 5 days
ago as reported by previous observer. The problem occurred
three times, the last being at HA = 2.5 hrs.
Repeately hitting W button both on slow and set motion speeds
would, after 10-30 seconds, cure the problem.
