MDM Trouble Report for 2010 Sep 6 Telescope: 1.3m Observer(s): Dietrich,Grier,Molina (OSU) Instrument: CCDS Problem(s) Encountered: At the end of the night, I wanted to slew the telescope from the position of 3C120 (RA = 04 33 11 Dec = +05 21 16 (J2000)) to the standard star G191B2B (RA = 05 05 30 Dec = 52 49 52 (J2000)). However, the tracking went off and an error message was displayed 'dec_m fatal error'. After switching the tracking on again, the telescope could be slewed back to the position of 3C120. ------------------------------ Submitted on 2010 Sep 7 [5:57:26]
