MDM Trouble Report for 2007 Feb 9 Telescope: 2.4m Observer(s): Joe Shields, Paul Peterson, Jonathan Robe (Ohio University) Instrument: CCDS Problem(s) Encountered: At 11:45 pm one of the CCDS frames showed anomalous, strong pattern noise. Subsequently CCDS stopped writing output data files to disk. After two exposures were completed but the resulting files did not appear, we executed runinit in prospero (it was last executed during the afternoon). The two missing files magically appeared on disk at this point (!) and subsequent files were correctly written to disk. The pattern noise did not repeat. If you want to look at the data files in question, they reside in /lhome/data/j020709; the frame with noise is no. 28 and the resurrected frames are no. 29 and 30. ------------------------------ Submitted on 2007 Feb 9 [7:06:55]
