MDM Trouble Report for 2002 Apr 13 Telescope: 2.4m Observer(s): Crotts (Columbia) Instrument: Mrk III/Echelle Problem(s) Encountered: Guider died for no apparent reason; PCGUIDER would not recognize star despite it being centered in guide box on TV monitor. Rebooting computer would not help. Jules and I jiggled frame grabber card and ribbon connector to DTI box, and PCGUIDER recognized star but would not send error signals to telescope. Jiggling them again got both functions to work again. ------------------------------ Submitted on 2002 Apr 14 [4:52:29]
