MDM Trouble Report for 2015 Jun 12

Telescope: 2.4m
Observer(s): Zinn, J., Wilber, A., Neric, M. (OSU, ASU)
Instrument: OSMOS

Problem(s) Encountered:
Saturated the CCD during sky flats in both twilight and sunrise hours, resulting in 'icicles' of saturated pixels on the top and bottom of the CCD.

I called cleansnap several times over the course of the observing run, and seemed to clear the CCD for the more important science frames.
