OSU/RC Queue Observing UTC 2011 Sept 26
(civil date 2011 Sept 25/26)
=======================================

Observers: R. Pogge, R. Stoll, S. Chung (OSU), D. Berg (UMN)
Observing Assistant: David Gonzalez-Huerta
Support Astronomer : Dave Thompson
Instrumentation    : 

Instrument: MODS

Summary:

First several hours of evening spent checking out MODS with new guide camera 
attached.  Guiding and WFS working well.  

Details:

Mirror several degrees out of equilibrium due to MODS work inside dome; David 
applied gross focus corrections by hand after pointing.  

Guide preset initially challenged by guider grabbing bright edge of pickoff 
mirror.  Reduced guiding ROI to fend off this problem in the future.

On-axis active preset successful first try.  ROI, center, and hot spot 
reasonably accurate.  

05:40 -- First images on the science camera during on-axis preset.  0.8" red 
         1" blue.

Off-axis active preset successful.

05:58 -- First images on the science camera during off-axis preset.  
         Wavefront corrections working correctly for off-axis.

06:18 -- testing MODS imaging mode.  Need to insert a pause for wavefront 
         convergence.  

         Beginning to get clouds.  When 

06:52 -- Closed telescope due to clouds 

08:30 -- Reopened, pointed

08:39 -- Doing acquisition on OSU_FeIIAGN/IZw1 
         Failed.   BAD GUIDE STAR LOCATION.

      -- Tried acquisition on OSU_FeAGN/Mkn957.  Failed, again guide star out
         of guide probe travel region.

08:52 -- hacked and redid IZw1.    We are way out of focus; the temperature 
         was changing rapidly.  Collimating on Persson standard star.

09:02 -- Resent hacked IZw1 preset.
09:10 -- began IZw1 obs script

09:34 -- Acquisition on UM RMHstarsM33_VarAW

09:39 -- Began UM RMHstarsM33_VarAW obs

10:23 -- Acquisition on standard star g191b2b

10:28 -- Began Standard star obs g191b2b 

10:33 -- Acquisition on UM M33 B324

10:47 -- Began UM M33 B324W obs script.  There are some clouds.   

10:56 -- Started three 300 sec exposures on M33 B324W due to bad seeing and clouds, using the MODS control panel GUI.  Purpose was to demonstrate use of MODS control panel to Dave Thompson, and teach how to observe outside of the scripts.
  Jump in the seeing from 1 arcsec to 1.4 arcsec.  

11:14 -- Acquisition on UM RMHstarsM33_FHyperW_ls.  Failed because guide star was lost due to clouds. 
  
11:28 -- Telescope closed -- clouds.

11:40 -- Beginning calibration data including arc lamp data with 0.6 arcsec slit, grating flat fields, and biases.
