MDM Observatory 1.3m Telescope Observer's Report for 2003 Mar 31

Observer(s): Martin Bureau, Davor Krajnovic
Institution(s): Columbia, Leiden

Instrument: Echelle f/7.5 direct imaging

Worked for 11 hours (all night)
Conditions were Mixed most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 1.4 arcsec, Cirrus, Winds Calm
   Mid: Seeing 1.9 arcsec, Clear, Winds Calm
   End: Seeing 1.5 arcsec, Clear, Winds Calm

Observing Summary:

Proceeded with our main project, obtaining long exposures on a number of galaxies (6.5 objects completed). The conditions were generally very good but a few occasional cirrus. The seeing was very good at the beginning (close to 1 arcsecond) but average for the rest of the night (1.5 to 2 arcseconds).

Unfortunately, we again lost a lot of time due to  wild slewing  of the telescope, as reported in previous nights. This always happens when pointing around 0-10 deg in DEC and slightly west of the meridian. Unfortunately, it is hard for us to avoid this region since most of our objects are in Virgo (RA=12-13, DEC=0-15).
