=======================================

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

Instrument: LBC

Summary:

...

05:01  Start collimating 

05:24  OSU_monitor N6946 focus (did not do co-pointing) 

05:36  Starting OSU_monitor N6946a OB 

06:12  OSU_monitor N925 focus and co-pointing

06:25  Starting OSU_monitor N925 OB.   

06:56  Had to restart LBC because it crashed.  Reason unknown.  

Important -- make sure to close and restart ds9 prior to running
lbcrangebal.  

Update -- Rick has given Dave a version of RB_Science modified so that
running an IRAF task (such as lbcrangebal) will no longer clobber the
existing RB_Science ds9 window.  In order to run IRAF tasks, just open
a separate ds9 window from within IRAF.


07:04  Co-pointing and collimating on N925 

07:09  Starting N925 OB again. 

07:22 There was a rotational shift between two sets of images (1.7
deg), though both images before and after the rotation jump appear to
have good PSFs.  Reason unknown, but Dave says LBC sometimes does
this.

07:35  Co-pointing and collimating on UVaAnd6 

07:48  Starting UVa_A and6_3 OB 

08:24 Collimating on UVaAnd6 (no co-pointing since we are staying in
the same field)

08:26  Starting UVa_A and6_2 OB 

08:43 Noticed that guide star on the blue channel shows a lot of
abberation in the g-filter.  However, the final g-band image looks
okay (not great).  Stars are not completely round but similar to
previous images.  Continue with OB.  Guide star for the next filter in
the blue channel looks fine.

Note Added: Dave & Rick inspected the technical chip images from
during this time, and it appears that the blue guider postage stamp
was showing a galaxy in the field.  The star images on the tech chip
images were nice and round.  We do not understand how they pick which
guide object to show in the postage stamp view.


09:00  Collimating on UvaAnd6 

09:05  Starting UVa_A and6_1 OB 

09:48  Co-pointing and collimating Uva_A and22

09:53  Starting Uva_A and22a OB 

10:45  Collimating on Uva_A and22a

10:50  Starting Uva_A and22b OB 

11:40  Observations completed at twilight.
