MDM Observatory 2.4m Telescope Observing Report for 2009 Aug 24

Observer(s): John Thorstensen
Institution(s): Dartmouth

Worked for 6 hours (last half of the night)
Conditions were Mixed most of the night.
Problems were encountered, see the separate trouble report for details.

   Clouds from start until 11.

   Mid: Seeing 1 arcsec, Patchy Clouds, Winds Calm

Observing Summary:


Night started with lowish clouds and the occasional raindrop --
monsoon is still with us -- but gradually cleared after about
11 PM.  Never cleared up completely, but got pretty good, and
the seeing was quite good.  

The telescope and instrument behaved very well, except for a 
reluctant mirror cover, described in the trouble report.  The 
dome came back to the contacts perfectly at the end of the night,
even though I'd been jumping around a fair amount.  Indications
are that the inaccurate dome really is cured.
