PLAN ---- We are shut down by an autonomous SCS 107 run at ~257:01:06, due to high E130 rates. Next Comms: 257:2035 to 2225 258:0325 to 0425 258:1240 to 1440 258:2040 to 2240 259:0345 to 0445 259:1650 to 1850 259:2245 to 2345 260:0245 to 0345 Orbital events: 2005:257:18:15:16.047 843 EPERIGEE ORBIT PERIGEE 2005:259:02:00:04.378 844 EAPOGEE ORBIT APOGEE 2005:260:09:43:05.542 844 EPERIGEE ORBIT PERIGEE 2005:261:17:28:01.102 845 EAPOGEE ORBIT APOGEE 2005:263:01:11:49.149 845 EPERIGEE ORBIT PERIGEE 2005:264:08:55:58.113 846 EAPOGEE ORBIT APOGEE 2005:265:16:40:20.574 846 EPERIGEE ORBIT PERIGEE EVENTS ------ Status at LOS, 257:12:09, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 0 RA = 36.032 deg Dec = -4.227 deg ROLL = 90.001 deg Format = 2 OBSID = 6390 interrupted XLSSJ022404.

EPH temp 94.86 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day. No issues. SCS 107 ran autonomously at ~257:01:06, due to high E130 rates. SCS 107 run was nominal. We will run the pre-approved CAP to disable SCS 29 today. Star Selection working group meeting cancelled for today. Radiation Telecon: Following the status meeting we conducted a radiation telecon. We expect a CME to hit tomorrow, and prevent a restart until, very roughly, late tomorrow night. Our "Plan A" is to uplink and restart following the comm pass starting at 258:2040 GMT, i.e., 4:40pm EDT tomorrow. We plan to rework the schedule to start with the obsid 6221 of EGS-6. This requires that we run a maneuver only load today to a more favorable pitch for cooling EPHIN prior to the EGS-6 observation at ~60 deg pitch.
