SCS 107 enables and activates SCS 29 as a contingency operation. - 1036F, 220/0117z | 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): Solar activity is expected to be very low with a chance for a C-class flares on day one (10 Aug) and expected to be very low with a slight chance for a C-class flare on days two and three (11 Aug, 12 Aug). Radiation (Geophysical Activity): The geomagnetic field is expected to be at quiet to unsettled levels on day one (10 Aug), quiet to active levels on day two (11 Aug) and quiet to minor storm levels on day three (12 Aug). MP: No issues. ENG: No issues. GOT: No issues.
