MDM Observatory 2.4m Telescope Observing Report for 2017 Jan 19

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

Instrument: modspec + echelle CCD

Worked for 1 hours (part of the night)
Conditions were Overcast most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Seeing 1-2 arcsec, Patchy Clouds, Winds Moderate
   Mid: Fog/Low Clouds, Winds Moderate
   End: Fog/Low Clouds, Winds Moderate

Observing Summary:

The very grim weather of the morning cleared up partially, with 
big clear spots during the day.  Mid-level cloud coverage became
more extensive around dinnertime, but the setting sun was visible 
under the cloud deck. After twilight there were some fairly 
good holes drifting by, so I opened to spear-fish a bright target,
and succeeded in getting one -- one! -- usable spectrum.  Doing
this while struggling with a glitchy telescope (tracking stopped
once) proved to be too much, so I closed up after a short while.
Fog rolled in a few hours later bringing the curtain down 
definitively.

There is a storm coming that will wipe out the last nights of
my run, save possibly Sunday, so I decided to leave early 
(which I almost never do).
