| 260/1808z | Disable SCS 29
SCS 29 controls the spacecraft loads during eclipse operations and will only
be active during the entire eclipse season. 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.
[1036E](/occweb/web/webapps/ifot/ifot.php?r=flightops&t=properties&format=sheet&id=934810)
| 260/1811z | 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 moderate with a slight chance for an X-class
flare on day one (17 Sep) and expected to be low with a chance for M-class
flares and a slight chance for an X-class flare on days two and three (18 Sep,
19 Sep).
