Running dofpia on N2403focus field  

UT0306 
Going to WT10_290 to run lbcrangebal 
only red image appeared in /newdata, trying again

UT0320
Back to N2403focus for dofpia
Est seeing 0.7" red, 1.7" blue 

UT0326 
Running N2403 
DIMM is 0.86"

UT0335
slewing to M81, running dofpia

UT0341
Running M81a
Looking through some clouds... clouds got worse so we aborted the last exposures

UT0351
Slewing to N3489, hoping this field won't be as plagued by clouds - this object is okay
Est seeing 0.8" red, 1.7" blue
DIMM is 0.69"

UT0405
Running N3489

UT0444
Slewing to N3627, running dofpia
Est seeing 0.7" red, 2.0" blue (according to dofpia)
DIMM is 0.73"

UT0449
Running N3627

UT0530
Slewing to N4826, running dofpia
Failed... Mostly cloudy

UT0540
All of our targets are behind clouds
  taking a break to wait for clouds to clear up a little

UT0650
Things are clearing up a little
Running dofpia for N4826

UT0655
Running N4826
DIMM is 1.1"

UT0720
we might be looking through some cirrus

UT0733
Slewing to N4449... nope, blocked by clouds
Downtime due to clouds

UT0850
Trying a sucker hole, slewing to N5194
Nope, still too cloudy

UT0920
dofpia started to look better

UT0927
Running N5194
the DIMM is going in and out with clouds...

UT0950
Last couple of images (lbcr.20130505.094457 & lbcr.20130505.094850) completed blanketed out by clouds -> pausing script
I think the paused exposures ended up getting nixed.
Resumed script ~UT1010
These images (the first ones after resuming the script) may be problematic & should be checked: lbcb.20130505.100633, lbcr.20130505.100623

UT1020-1050
slewed to a new target and canceled dofpia while it was running
then LBC locked up and would not let us start a new OB even though we had clicked stop on the LBC GUI.  Ended up needing to get Dave to login and restart LBC.

UT1055
Too cloudy to take twilight flats
Closing.
