SOT shift report 2001-12-03 M865 Shift M865 Duration: 3 Dec 2001 18:00 EST - 3 Dec 2001 20:00 EST 3 Dec 2001 23:00 GMT - 4 Dec 2001 01:00 GMT SOT Lead: Tom Aldcroft ======================================== Plan ---- Perform CAP 771 to attempt to clear the EPHIN HW failure flag, by patching OBC-A to so that the Radmon Init Process is run when Radmon is enabled. Events ------ 23:00 AOS on DSS-27 23:21 Run CAP 772 to enable auto unloading 23:24 Start CAP 771 - SCS 107 and radmon are disabled 23:26 Perform CAP 750b to dump OBC EPHIN variables 23:32 Load OBCA_150_PR139.CLD to patch Process_Enable 23:33 Re-dump memory -> Error in memory has gone from 2 to 0 23:35 Radmon enabled 23:36 Memory dump script run repeatedly for ~18 minutes 23:56 Radmon disabled 23:57 SCS 107 enabled Notes/Issues/Problems --------------------- - CAP 771 was successfully run and the EPHIN HW failure flag was reset as expected. Several full cycles of the EPHIN counter (which goes from 0 to 7) were observed via repeated memory dumps and no errors were observed for either the EPHIN or EIO. - The DEC0401B load was uplinked and started. - Radiation rates are low Snapshot -------- The snapshot matches the expected configuration: UTC 2001:338:00:40:19 (Dec 4) f_ACE 7.15e+02 F_CRM 2.67e+07 Kp 3.7 R km 86254D OBT 2001:338:00:39:54 CTUVCDU 2728921 OBC s/w NRML FMT2_NORM CPEstat NORM OBT 123813594.21 ONLVCDU 2728912 OBC Errs 0 OBSID 61396 EPState SUN SIM TTpos -99616 HETG Angle 79.46 PCADMODE NPNT RA 254.423 Bus V 29.77 SIM FApos -535 LETG Angle 4.46 PCONTROL NPNT Dec 35.330 Bus I 30.01 AOFSTAR GUID Roll 353.287 ACA Object SSSSSSSS Dither ENAB HRC-I HV OFF ACA ImFunc NNNTTTTT Dith Yang -6.55 Yaw Rate 0.08 HRC-S HV ON ACA CCD Temp -10.8 Dith Zang -0.54 Pitch Rate 0.12 OBSMode NEXT ACA Int Time 1.698 Roll Rate -0.08 Door OP UNAC AOACSTAT OK FSS SunBeta SUN Door CL UNAC FSS Alfa 1.97 Batt 1 SOC 100.00% Avg HRMA Temp 70.63 FSS Beta 32.04 Batt 2 SOC 100.00% ACIS Stat7-0 66 Avg OBA Temp 51.29 SA Resolv 57.75 Batt 3 SOC 100.00% Cold Rad -127.9 OBA Tavg Fault NFLT SA Sun Pres ILLM Warm Rad -84.4 OBA Trng Fault NFLT +Y SA Amps 14.49 RadMon DISA HRMA power 31.70 SCS 128 ACT -Y SA Amps 15.26 EPHIN Geom LARG OBA power 126.90 SCS 129 DISA +Y SA Temp 116.22 E150 33.7 SCS 130 DISA -Y SA Temp 116.58 E300 0.6 Roll Mom. -0.002 SCS 107 INAC E1300 0.0 Pitch Mom. 1.992 UpL Cmd Acc 34827 EPH A-Leak 1.0200 P4GM 0.2 Yaw Mom. 0.823 Cmd Rej A 34 EPH B-Leak 0.3640 P41GM 0.0 Explanation Current Data: UTC 2001:338:00:40:19 (Dec 4) f_ACE 7.15e+02 F_CRM 2.67e+07 Kp 3.7 R km 86254D Currently scheduled FPSI, OTG : HRC-S LETG Costello Kp : 4.67 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 7.15e+02 Orbit Start Time : 2001:335:18:54:01 Geocentric Distance (km), Orbit Leg : 86429 D CRM Region : 2 (Magnetosheath) External Proton Flux (p/cm^2-s-sr-MeV) : 4.31030000000e+04 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 0.00000000000e+00 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 1.23612092403e+09 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 2.66629938000e+07
