MDM Observatory 1.3m Telescope Observing Report for 2011 May 11

Observer(s): S. Lepine
Institution(s): AMNH

Instrument: MkIII+Wilbur

Worked for 10 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.0 arcsec, Clear, Winds Calm
   Mid: Seeing 1.0 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.0 arcsec, Clear, Winds Light & Variable

Observing Summary:

Excellent night. This time the Decl. guiding behaved
and NS shaking was minimal, most likely due to relatively
low winds combined with wind control measures (doors and
dropout closed).

Tracking was systematically lost whenever a new pointing
was completed. It seemed to coincide with the moment the
dome had finished moving to the new position. Simple fix
is just to hit the tracking button again, an hit point to
move back to target.

Observed all night and got spectra of 33 young M dwarf
candidates.
