SCS 107 enables and actives SCS 29 as a contingency operation. SCS 29 should be disabled when outside of the eclipse season. This CAP should be executed after the last eclipse of the season, as directed by the EPS engineer. Additionally, this CAP may be used in the event SCS 107 is executed outside of eclipse season. [1036E] | 155/1131z | 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 expected to be very low with a slight chance for a C-class flare on days one, two, and three (04 Jun, 05 Jun, 06 Jun). MP: Jun0721a loads are approved, there is a TOO that if approved would interrupt schedule next week. ENG: No issues. GOT: No issues.
