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

00:00 -- Handover/start up. Got both LUCI and MODS set up. Plan is
         MODS for most of the night, then LUCI to observer a NIR
         transient.

02:00 -- Some issues with the telescope software, might get resolved
         while collimation is happening.

02:20 -- We're collimated, starting standard star G191-b2b.
         Conditions look great. Clear, seeing ~0.7".

02:45 -- Moving to ND_paloma. There appears to be a bug in modsAlign. We used
         the standard call twice (modsAlign -l <slitImage> <fieldImage>) and 
         DS9 failed to display any images and threw and uninformative error 
         message. We reran with the -y 7 option and everything worked. The
         trace of the object is a little low on the chip in the blue, but
         should be fine. The script was named with _PA120.acq, but actually
         uses -60 in the script. To avoid the potential for confusion, it
         is better to just name the script with the appropriate UT time.

04:45 -- Everything looks good, seeing still ~0.7", clear skies.

05:35 -- Moving to ASASSN-16lx. Conditions still great, seeing 0.8".
         The modsAlign -l option worked fine this time...

06:18 -- First exposure just came in. The blue frame has a lot of
         light near the corners of the chip. I haven't seen this
         before. Dave thinks it looks like amplifier glow, but he
         has not seen it this bright before. Olga and Dave are
         looking into it. Apparently it's in older data, so
         probably not a big issue.

07:00 -- Moving to AT2016ffh. Sky is still clear but we're kinda low
         in the sky, seeing creeping up a little to 1+".

08:30 -- Moving to AT2016fnr. Still clear, seeing ~1.1".
         Seeing fluctuated between 0.9" and 1.1".

09:50 -- Moving to AT2016ehy. Weather is great, guide star flux very steady,
         seeing ~0.8".

11:25 -- Switching to LUCI.
         Finished dark frames from earlier while waiting for ND_GW
         object to get a little closer to elevation limit.

12:10 -- Collimation at this elevation is proving difficult, but we did it.
         Potential issues with guide star location.

12:30 -- Trying H-band. LUCI1 image quality looks better than LUCI2.
         Script appeared to pause after img #0041 (not sure why), 
         tried to resume, seemed to work for one image, but got
         paused/hung again. Restarted the scheduler and resumed 
         script at exposure ~4.

13:24 -- H-band flat counts getting to ~5k, starting twilight flat script.
         Running twice for higher counts. Sky got bright fast, we didn't 
         get J-band flats.
