See https://cxc.harvard.edu/mta/SOT_reports/sot-shift.html Shift L8078. Start at 245:13:00 GMT PLAN ---- Return-to-science loads will be uplinked at the 2021/245 1430z comm upon a successful execution of the new CAP to retract LETG. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: 2 Supports completed in the last 24 hours (total time: 4.6 hours) 3 SSR dumps 1 CAP 1583, 244/1834z, Reset Last Move Success Flag and Retract LETG, If an OTG motion fails for any reason the Last_Sequence_Successful flag is set to False to inhibit future OTG motions. To re-enable OTG motions after the initial OTG motion error is corrected; the Last_Sequence_Sucessful flag must be reset to True. After the Last_Sequence_Successful is reset, a software retraction of the LETG will be commanded so that the final conditions can be verified in realtime. Step 17: Command 4OLETGERE - This command was not available on console. Radiation: Solar activity is expected to be very low with a chance for a C-class flares on days one and two (02 Sep, 03 Sep) and expected to be very low with a slight chance for a C-class flare on day three (04 Sep). MP: Sep0221 return to science load review today at 10:30am. Eng: The Last_Sequence_Successful flag was reset, a new CAP to retract LETG manually will be reviewed today and executed at the 2021/245 1430z comm. Upon successful execution of the new CAP, the replan loads will be uplinked during the same comm. GOT: No issues.
