MDM Trouble Report for 2013 Jul 12 Telescope: 1.3m Observer(s): Sarah Schmidt (Ohio State University) Instrument: Nellie (imaging) Problem(s) Encountered: No dramatic problems, these are more low-level issues that don't interfere much with observing: 1. At the beginning of the night, I had the same moisture problem as last night. I was able to dry it off using the compressed nitrogen but I lost 10 minutes of flats. I was surprised that it needed drying (as Tony said he had done it earlier in the day). 2. Weird CCD effect - vertical striping on the top 1/4 of the CCD - there are bad rows, but this is across the entire image. It is visible in image Jul13.0064.fit, for example. I couldn't tell if it was persistent and constant, but I don't remember it from my last observing run. If it is constant, then my data is fine. 3. ERROR mirror mirror neither open not closed (did not interfere with obs at all). ------------------------------ Submitted on 2013 Jul 13 [4:14:19]
