Moon phase: 

Summary: Plan was to start with LBC. There was a problem early on with a
         balance pump. Didn't lose much dark time but we'll have to postpone
         twilight flats. Observed a few fields with LBC but eventually
         clouds moved in and we couldn't observe much of anything. Switched
         to MODS at the end and did some calibrations, one science field,
         and a standard.

Minor technical issues: Some problem with balance pumps, going to take
                        an hour or two to resolve. Not going to be able
                        to do twilight flats at start. Issue track was
                        opened on lbcr image readout issues, but this
                        problem has apparently been encountered before
                        and the solution is to reboot LBCs.

Details (All times UT):
----------------------------------

00:00 - Handover ect. We're getting LBC set up, but there's
        a problem with a balance pump that needs to be resovled.

01:45 - Everything is set up and ready to go, we're moving to the
        OSU_M31 field. Wind looks like it will be borderline, but
        otherwise conditions like good. Seeing could be better.
        There is no focus/copointing finding chart for this object...

02:10 - Images are looking a little out of focus, so we're going
        back to refocus.
02:25 - Back to science field. Image quality still looking better in
        blue camera than red camera...odd.

02:45 - Moving to OSU_monitor/N628
        Conditions are good. Seeing fluctuating around 1".
03:30   Image quality deterioriated towards the end, so we went to
        refocus, and edited the OB to redo the last two exposures on
        each side.

04:00 - Moving to UVa_M33_GC/M33_Field3
        The PI did not include a copointing OB!! We tried generating one
        from the OT xml, but the observations were not configured
        correctly and we had to improvise.
04:25 - Starting the science OB.
        Something went very wrong with the readout on the red camera.
        We're going to redo focus and see if the problem persists.
04:50 - There's still something severely wrong with the lbcr images,
        so we'll try cycling the power. 
05:15 - Rebooted, refocused, back on science field, first set of images
        looks good.
05:20 - Wind caused the preset to fail. We're retrying, but may have to
        move to another target if it fails again.
06:00 - Refocusing.
06:40 - Image quality in blue camera suffering in the last few exposures.

06:45 - Moving to OSU_monitor/N672
07:15 - Focus and collimation took a while. Red looks good, but blue seems
        to me having some issues maintaining focus.
07:30 - Clouds may soon be a factor

08:00 - Starting OSU_monitor/N925.ob
        Clouds moving in.
08:20 - Unclear how useful these will be.

08:35 - Starting OSU_monitor/N2403
        Looking pretty hopeless, we're switching to MODS, but it doesn't
        look too promising for that either.

09:30 - Too cloudy, we'll do MODS calibrations and see if it clears up.

10:40 - Not looking too bad, we'll give it another shot.
        Moving to UVa_BCD_MODS/J0827
        We can at least see the object in the acquisition image, but
        the spectra will likely be low S/N at best.
10:50 - Started J0827.obs
11:10 - Continuum is quite weak but the nebular lines are clearly visible.
        This is going to be very close to zenith, so there may be some
        tracking issues toward the end of the fourth exposure.
        We added an exposure in case any were significantly affected
        by clouds or tracking issues.

12:15 - Moving to standard Feige34.
12:45 - Done for the night.
