Observation log for 09-10 January 2013

Projects Completed:
OSU_RVs
OSU_WD

Projects Not Completed:
OSU_monitor

Summary:
Decent seeing most of the night. Variable amount of cirrus throughout the night.  
Started with MODS and switched to LBC last half of the night.

acqMODS m35_w38028.acq
The slit image was slightly off after acq.  So we are redoing.  Don’t know why.

Computed Slit Alignment Offset:
  dX:   0.273 arcsec
  dY:  10.118 arcsec

Perhaps I should I noticed the dx was a little too high...

acqMODS m35_w38028.acq

Computed Slit Alignment Offset:
  dX:   0.044 arcsec
  dY:   2.491 arcsec

looks good this time, don’t know why it did not centroid well last time.

03:45:
execMODS m35_w38028.obs

The whole M35 series is being taken through various amounts of light cirrus.  
The seeing is 0.9 to 1.0 arcsec, slowly getting worse.

Cirrus getting heavier.

04:06
acqMODS m35_w74038.acq

For m35_w74038 the alignment was only a little off (sent images to PI and through 
slit image fits files).  Don brought up the point that this is a good test to see how 
sensitive you are to slight alignment for ordinary acquisition procedures so we 
observed this object with the alignment slightly off.  Now clearer than it was before.

Seeing not too bad: 1.0” or so in U, 0.75” in R.  Blue image quality is not as good as in the red.

*cirrus*
1” blue 0.8” red, maybe softening in B during the exposure series.  OB stopped after ~7 images 
out of 12 because of some problem with LBC.  Restart LBC.  Edit OB to run remaining images.  
Do refocus but not co-pointing.  Seeing after restart ~ 0.9” in B and R.
