SCS 29 controls the spacecraft loads during eclipse operations and will be active during the entire eclipse season. The only time SCS 29 will not be active in eclipse season is during the actual eclipse. [1036E] | 130/0301z | Clear EPS Glitch Counters The EPS glitch counters will increment if there is an issue found within the EPS subsystem. For example, a known problem with Battery Disconnect Circuit timing may cause occasional glitches when a disconnect pulse is detected in the charge cycle. This CAP will dump all glitch counter values, and if a counter increment has occurred all EPS glitch counters will be cleared. Radiation: Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (10 May, 11 May, 12 May). MP: May1721 loads in work, potential for TOO to be triggered that would affect current running loads. ENG: No issues. GOT: No issues.
