MDM Trouble Report for 2012 Apr 9 Telescope: 2.4m Observer(s): Kellen Murphy, Rebecca Santana (Ohio University) Instrument: R4K OSMOS Problem(s) Encountered: Error message encountered when trying to display fits file from iraf with DS9. ERROR: Cannot open device (node!imtool,,4096,4096) Flpr did not fix issue. Could not check seeing on Hiltner. Expect a reboot would remedy the problem but didn't feel that we needed precise seeing measurements for this data set, so chose not to risk it. Additional issue, at some point during operations the green start light on the TCS switch panel went out. Was still able to operate telescope, bulb issue? ------------------------------ Submitted on 2012 Apr 10 [5:22:27]
