TIMELINE (GMT day 299) ---------------------- 12:21UT command load 2A_IHV_DM00.cld uploaded to SCS 135 12:23UT SCS 135 enabled and activated. HRC team verifies 2IMONST=OFF and top and bottom plate steps set to 0 steps 12:24UT SCS 135 is disabled and cleared 12:25UT SCS 87 is disabled 12:26UT SCS 89 and SCS 90 are disabled. SCS 91 is inactive; SIM is at proper position; FMT1 is verified 12:27UT SCS 88 is disabled 12:28UT dither is verified; command load 2A_SDEFAULTB_135.cld is uploaded to SCS 135 12:30UT SCS 135 is enabled and activated; HRC verifies 2PREADS = IMAG and 2PREBDS = SPEC 12:46UT SCS 135 is disabled and cleared 12:47UT command load 2A_SHV_DM20_135.cld is uploaded to SCS 135 12:48UT Obsid is changed to 62649; HRC verifies COBSRQID = 62649 12:49UT SCS 135 is enabled and activated; deadman timer begins at 12:50UT 12:51UT SCS 93 is activated; HRC verifies 2SPONST = ON 12:55UT start script 2_HV_S_UP_VERY_SLOW; HRC verifies 2SPBPAST = 19 and 2SPTPAST = 8 13:02UT HRC verifies 2SPBPAST = 54 and 2SPTPAST = 43; half voltage 13:06UT SCS 135 is disabled and cleared; deadman timer is cancelled 13:07UT SCS 88 enabled and inactive 13:08UT script 2_HV_S_UP_VERY_SLOW resumed; HRC verifies 2SPBPAST = 62 and 2SPTPAST = 51 13:35UT HRC verifies 2SPBPAST = 89 and 2SPTPAST = 78; total and valid event rates > 0 14:03UT HRC verifies 2SPBPAST = 105 and 2SPTPAST = 93; total rates ~ 225 c/s and valid rates ~ 110 c/s 14:36UT script 2_HV_S_UP_VERY_SLOW is stopped and exited. Data at nominal settings will be collected until SCS 88 is activated 15:20UT HRC verifies that SCS 88 has been activated and the HRC-S is at half voltage: 2SPBPAST = 54 and 2SPTPAST = 43 UTC 2020:299:12:18:02 (Oct25) f_ACE 2.39e+02 F_CRM 1.00e+00 Kp 1.7 R km 126810A OBT 2020:299:12:17:30 CTUVCDU 1196543 OBC s/w NRML FMT1_NORM CPEstat NORM OBT 720015450.52 ONLVCDU 1196536 OBC Errs 0 OBSID 24645 EPState SUN SIM TTpos -99615 HETG Angle 78.34 PCADMODE NPNT RA 332.163 Bus V 28.36 SIM FApos -715 LETG Angle 76.46 PCONTROL NPNT Dec 45.761 Bus I 23.40 AOFSTAR GUID Roll 242.006 ACA Object FFFSSSSS Dither ENAB HRC-I HV ON ACA ImFunc TTTTTTTT Dith Yang 16.07 Yaw Rate -0.14 HRC-S HV OFF ACA CCD Temp -11.2 Dith Zang 9.05 Pitch Rate 0.10 SHLD HV 8.0 ACA Int Time 1.698 Roll Rate -0.13 EVT RT 255 AOACSTAT OK FSS SunBeta SUN SHLD RT 4844 FSS Alfa 12.67 Batt 1 SOC 100.00% Avg HRMA Temp 72.10 FSS Beta -31.99 Batt 2 SOC 100.00% ACIS Stat7-0 66 Avg OBA Temp 64.35 SA Resolv 121.74 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 11.60 RadMon ENAB HRMA power 61.40 SCS 128 ACT -Y SA Amps 11.41 OBA power 70.20 SCS 129 ACT +Y SA Temp 115.12 SCS 130 ACT -Y SA Temp 115.12 Roll Mom. 14.157 SCS 131 ACT Pitch Mom. -6.747 SCS 132 ACT Ephin Temp 0.0000 UpLCmdAcc 38172 Yaw Mom. -7.567 SCS 133 ACT EIO Temp 0.0000 Cmd Rej A 118 PMTANKP 132.547 SCS 107 INAC EPH temp 133.94 IRU2G2 curr 112.80 M Unload MON IRU2G1 curr 93.60 Roll Bias 0.4580 TSC Move STOP Prop. line 03 162.13 Pitch Bias -2.4977 CTX A PWR 36.49 FA Move STOP Prop. line 04 138.53 Yaw Bias -1.5075 CTX A Volts 3.50 OTG Move DISA Explanation Current Data: UTC 2020:299:12:18:02 (Oct25) f_ACE 2.39e+02 F_CRM 1.00e+00 Kp 1.7 R km 126810A Currently scheduled FPSI, OTG : HRC-S NONE Estimated Kp : 1.7 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 2.39e+02 GOES-R P4 flux, in RADMON P4GM units : 0.120 GOES-R P7 flux, in RADMON P41GM units : 0.018 GOES-R E > 2.0 MeV flux (p/cm^2-s-sr) : 1030.0 Orbit Start Time : 2020:298:17:59:01 Geocentric Distance (km), Orbit Leg : 126622 A CRM Region : 2 (Magnetosheath) External Proton Flux (p/cm^2-s-sr-MeV) : 6.2597e+02 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 0.0000e+00 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 3.1161e+09 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 3.8683e+07 Due to transition to GOES-16, what used to be P2 is now P4 and what used to be P5 is now P7 This message will dissappear in 01/31/2021
