Apart from a fwe minor niggles with the VERY occasional SISPI interlock tripping, two faults to note are:
(a) There were two shutter alarms during the night (quite close together in time). The first occured at 04:15 local, the second at 04:42 local -- see elog #173878
(b) at 00:25 local, the DTS process fell over, and I alerted SDM to it. Rob Seaman was very fast and efficient, and had re-started the daemon within 20-minutes or so. Affected exposures were DECam_00292404 --> 414.

Here is a summary of the night's observations:
(a) Slewing very close to Jupiter, we sat on an Ecliptic plane field for just over an hour in order to test the VR filter, and provide input data for a solar system moving object pipeline (see elogs #173648 and #173656).
(b) we observed an SPT field for one of Alfredo Z.'s projects, using a series of 100-seconds griz exposures (see elog #173713).
(c) Several g-filter images were acquired for NOAO project 2014A-0608, albeit with a DTS failure mid-series (see #log 173735).
(d) In such bright Moon conditions, I was eager to see how the new VR-filter responds to high sky background, and so we took a series of images in all filters (ugrizY for comparison to the VR-filter) at the same hour angle as the Moon, but in a range of Moon distances -- essentially, slewing through a range of declinations (see elog #173767).
(e) I was most eager to complete the Aberration Mapping for Roberto T. and Rolo C., and so that was completed (see elog #173853 and 173878).
(f) Finally, we finished off with some z-filter imaging for one of my own programs (2013B-0612), running all the way until the Sun's altitude was -12 degrees or so (see elogs #173958, #173963, #173968 and #173974).
Overall, a fine, fine night.
