MDM Observatory 2.4m Telescope Observer's Report for 2006 Jun 14

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

Instrument: echelle direct + 2 in FW

Worked for 8 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 arcsec, Cirrus, Winds Moderate
   Mid: Seeing 0.8 arcsec, Cirrus, Winds Light & Variable
   End: Seeing 0.8 arcsec, Clear, Winds Light & Variable

Observing Summary:

Weatherwise, a much better night than last night -- cirrusy at
first, but eventually these cleared away (there was a bright 
moon 2nd half).  Before sunset there was a layer of what appeared
to be forest-fire smoke far to the west -- satellite images 
suggested that this was from a fire in northern Baja.

There were three problems; in order of seriousness they are
(a) the UPS evidently does not work; (b) continued clusters of
stubbornly persistent asynchronous read errors; (c) some 
electrical noise is evident in low-background CCD images.  
Details are in trouble report.

Note to Bob -- please go ahead and change the instrument as
orignally scheduled.
