Moon phase: 

Summary: Half night (TSIP second half, handover at 07:04 UT).
         Skies looking good at start. MODS2 is back up and running
         so observations were done in binocular mode.

Minor technical issues: Several telescope pointing/shell/mirror crashes
                        mostly because we were pushing close to elevation
                        limits (although the final mirror panic was at a
                        reasonably high elevation).

Completed Programs:

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

00:00 - Handover/etc. Looks like the weather will cooperate tonight.
        Plan will be ASASSN17jz as soon as its dark and push it to
        the elevation limit, a standard star, then a faint SN Ia host, 
        and lastly the remaining UVa BCDs.

01:15 - Getting collimated near ASASSN17jz.

01:40 - On target, but this is very close to the elevation limit;
        we're going to have to stop at some point.

        Ended up with 9 min of exposure time on each side.

02:00 - Standard star Feige110. There was a mix up with the thru
        slit image sequence, but the spectra are fine.

02:35 - Trying to set up on GALEXASCJ011415. This is another low
        target (but above limit and rising). The both shells rip'd,
        and the left mirror panicked; recovery will take a few minutes.

02:45 - We're going to try UVa_BCD_MODS/J0007 first to avoid these low
        elevations.
02:46 - Left mirror panic.
03:00 - Trying again, have to do another pointing check.

03:20 - J0007.obs.
        Conditions look great (sub-arcsec seeing, no wind, no clouds)
        and should stay that way for the rest of the night.

03:45 - We're taking LBC biases while this is going.

04:10 - For some reason the MODS1 blue exposure sequence stopped.
        We're doing the additional exposures by hand. These scripts were
        prepared with the OT and have an unusual format. We ran them on
        previous nights with MODS1 alone and they seemed to execute fine,
        but tonight there seems to be some issues, possibly due to 
        the fact we're doing binocular mode.

05:00 - GALEXASCJ011415
        The collimation isn't great this low in the sky.
        Looks like very faint Halpha and maybe OIII visible.
        This worked out to end right at the elevation limit.

06:35 - Moving to standard GD71

06:49 - We got 2 exposures in and the left mirror panicked (again), so 
        looks like we're going to call it a night.

07:00 - Handover to TSIP
