HUBBLE SPACE TELESCOPE - Continuing to Collect World Class Science DAILY REPORT #4970 PERIOD COVERED: 5am November 10 - 5am November 12, 2009 (DOY 314/10:00z-316/10:00z) OBSERVATIONS SCHEDULED WFC3/IR/S/C 11929 IR Dark Current Monitor Analyses of ground test data showed that dark current signals are more reliably removed from science data using darks taken with the same exposure sequences as the science data, than with a single dark current image scaled by desired exposure time. T ...Continue Reading

HUBBLE SPACE TELESCOPE - Continuing to Collect World Class Science DAILY REPORT #4967 PERIOD COVERED: 5am November 5 - 5am November 6, 2009 (DOY 309/10:00z-310/10:00z) OBSERVATIONS SCHEDULED COS/NUV/FUV/WFC3/UV/IR 11528 COS-GTO: Studies of the HeII Reionization Epoch Intergalactic Ly-alpha opacity suggests that H I was reionized at z ~ 6, while He II reionization was delayed to z ~ 3. Both epochs are slightly in disagreement with recent (WMAP-3) inferences from the CMB optical dep ...Continue Reading
