The MEGS-B duty cycle was altered to include 3 hours of continuous observations plus 5-minute exposures for all other hours starting on August 16, 2010 (day 228). Prior to that, MEGS-B had only 15-16 minute observations each day. Approximately once per month EVE is commanded to perform a MEGS-B Flare Campaign, where MEGS-B is exposed continuously for 24 hours.
