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. [1036F](/occweb/web/webapps/ifot/ifot.php?r=flightops&t=properties&format=sheet&id=1012953) | 199/1810z | 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 likely to be low with a slight chance for an M-class flare on days one, two, and three (20 Jul, 21 Jul, 22 Jul). Radiation (Geophysical Activity): The geomagnetic field is expected to be at quiet levels on day one (20 Jul), quiet to active levels on day two (21 Jul) and active to minor storm levels on day three (22 Jul). MP: No issues. ENG: No issues. First eclipse of the season now completed. GOT: No issues.
