HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT      #4910 PERIOD COVERED: 5am August 14 - 5am August 17, 2009 (DOY 226/09:00z-229/09:00z) OBSERVATIONS SCHEDULED WFC3/UV 11908 Cycle 17: UVIS Bowtie Monitor Ground testing revealed an intermittent hysteresis type effect in the UVIS detector (both CCDs) at the level of ~1%, lasting hours to days. Initially found via an unexpected bowtie-shaped feature in flatfield ratios, subsequent lab tests on similar e2v ...Continue Reading
