MDM Trouble Report for 2007 Jun 10 Telescope: 2.4m Observer(s): McGreer (Columbia) Instrument: Echelle Problem(s) Encountered: At 3am, the telescope lost guiding. The TCS monitor displayed a DEC encoder not responding message. I tried to use the hand paddle to move the telescope, but it was unresponsive and at that point displayed RA or DEC encoders not responding . I went to the nearest bright and reset the encoders, from then on it behaved normally. ------------------------------ Submitted on 2007 Jun 10 [4:55:57]
