MDM Trouble Report for 2014 Jan 20 Telescope: 1.3m Observer(s): Mudd and Simonian (Ohio State) Instrument: CCDS Problem(s) Encountered: During observation, the TCSLINK on the Prospero Status window turned red for inactive . Tried calling tscstatus and tcinit, which initially worked, but during the next exposure/object, their were multiple issues in observing scripts indicating that there was not proper communication with tcs. Any other commands would then hang, so we pointed the telescope to zenith and began a restart of the IC computer. After several attempts, we got the tcslink reestablished and were able to continue observing. On our second object after getting started again, however, once again our scripts started to hang and Prospero indicated that it could not communicate with telescope. We then closed all the tcstools and started from scratch again (without restarting IC computer) and were able to get control back. ------------------------------ Submitted on 2014 Jan 21 [6:33:46]
