This may have been caused by the high winds of 20-25 mph. We also observed a multi-slit mask. Everything ran smoothly. No problems to report. We also closed the dark hatch and filled the dewar on the 1.3 m before heading to bed in the morning. ------------------------------ Submitted on 2015 Oct 10 [4:31:42]
