MDM Trouble Report for 2015 Jun 24 Telescope: 1.3m Observer(s): Halpern (Columbia) Instrument: Templeton Problem(s) Encountered: When observing at HA=-2, Dec=+06, the guider camera stopped guiding. After fiddling with the computer for a while, I finally noticed that also the science images were coming out blank, i.e., the shutter in the filter wheel wasn't working. At this point, it became obvious that there was a power problem. The power cables for both devices had become loose at the same time. Reseating the power plugs in the power strip fixed both. There wasn't any wind or other force that I could hear that was responsible for this event. ------------------------------ Submitted on 2015 Jun 25 [0:48:51]
