MDM Trouble Report for 2011 Mar 21 Telescope: 1.3m Observer(s): M. Boettcher, H. Zhang (Ohio University) Instrument: 4K Problem(s) Encountered: The TCS link broke down. The telescope didn't react to a filter command from prospero, and the tcs agent froze up. Closing and re-opening the TCS agent, re-initializing the TCS, (telinit, tcinit, ...) didn't solve the problem, neither did a complete shutdown of the data acquisition programs and starting from scratch (ISIS -> TCS Agent -> Caliban -> Prospero). We couldn't home the telescope or close the mirror covers. ------------------------------ Submitted on 2011 Mar 21 [1:58:43]
