See https://cxc.harvard.edu/mta/SOT_reports/sot-shift.html Shift L9090. Start at 162:13:00 GMT PLAN ---- JUN1124A return-to-science loads uplink at the 8pm comm, following go/no-go tag-up at 7:45pm. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: 9 Supports Completed over the weekend (Total time: 20.7 hours) 9 SSR dumps Loads good through: 2024:166:03:15:02 At the day 160 03:00z comm (Friday night), SCS-107 was observed to have run at 160:02:29:29z (10:29 EDT). This was in response to prompt particles from an M9.7 flare from AR 3697 at 01:49z. The science instruments were confirmed safe during the real-time communication pass. CAP's: - 893B, 160/0331z, 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. Additionally, this CAP may be used in the event SCS 107 is executed outside of eclipse season. - 1746, 160/2013z, Command a 4-CCD ACIS-I ECS measurement via RTS, template version 1.8 Command ACIS to execute an ECS measurement using an RTS. Radiation rates reported by the HRC Anti-Coincidence shield or its proxy are below the SCS-107 trigger values, or close enough (as defined by the Flight Director) and trending downward, to prevent another SCS-107 trigger run. Science runs will not commence for some time. Therefore, the time can be used for making an ECS measurement with ACIS. The CAP will change the TLM FMT to 2 if necessary, enable SCS 107 if necessary, change the OBSID, and uplink a command load that contains an RTS to enable RADMON and to execute an ACIS ECS measurement. ACIS will integrate for a user-selectable time and then the RTS will disable RADMON, and stop the ACIS ECS measurement and prepare ACIS for entry into the radiation belts. This CAP contains contingency steps 15-17 in case the RTS has started execution and it needs to be interrupted manually during a realtime COM. Radiation: GOES proxy rates are substantially below threshold and falling; ACE P3 rates, currently at ~15,000, are still rising but are expected to turn over later today (as they already have at higher energies). An X1.5 class flare was detected this morning from the departing AR 3697 (3664). A CME associated with this event is heading to the west and away from Earth. Solar activity is expected to be moderate with a chance for X-class flares on days one and two (10 Jun, 11 Jun) and expected to be low with a chance for M-class flares and a slight chance for an X-class flare on day three (12 Jun). MP: JUN1124A return-to-science load review by 1:30pm. ENG: No issues. GOT: No issues.
