MDM Observatory 2.4m Telescope Observing Report for 2009 Jun 03

Observer(s): John Tobin and Hsin-Fang Chiang
Institution(s): Michigan

Instrument: TIFKAM

Worked for 9.0 hours (all night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Seeing 0.9 arcsec, Clear, Winds Moderate
   Mid: Seeing 1.0 arcsec, Clear, Winds Moderate
   End: Seeing 0.8 arcsec, Overcast, Winds Calm

Observing Summary:

Overall a pretty decent night. Conditions were
good until about 3am when clouds started moving in. Seeing
was reasonably good at least 1  for the entire night and at times
subarcsecond. We imaged several target fields and took spectra of 
two protostars and two Hipparcos standards.

The J-band filter still not parfocal with the H and Ks bands.
Though we were only observing J-band at high arimass which may
affect the focus. I haven't used J-band very much so this
might be a  feature  of the instrument I wasn't aware of.
