[893B] | 245/0143z | 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. DSN DR's Created: DR Number| Station| Problem| Cause| Action ---|---|---|---|--- [M118259]|DSS-65| No telemetry at BOT| Antenna not able to lock up to s/c| Re-sweep,break lock, re-lock Radiation (Solar Activity): Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (02 Sep, 03 Sep, 04 Sep). CME passage observed on Saturday evening and elevated radiation rates observed over Monday afternoon. ACE P3 currently around 4-5k counts. Radiation (Geophysical Activity): The geomagnetic field is expected to be at active to severe storm levels on day one (02 Sep), quiet to active levels on day two (03 Sep) and quiet to unsettled levels on day three (04 Sep). Protons are likely to cross threshold on day one (02 Sep) and have a slight chance of crossing threshold on days two and three (03 Sep, 04 Sep). MP: Science resumption command loads out for review. ENG: Nominal run of SCS107. SCS29 disabled. Will be running two pre-approved CAPs for OBC memory dump. GOT: No issues.
