See https://cxc.harvard.edu/mta/SOT_reports/sot-shift.html Report M8384 Start at 186:21:20 GMT = 5:00pm, Tuesday July 5 End at 186:23:50 GMT = 7:50pm, Tuesday July 5 HRC Personnel: Dan Patnaude, Ralph Kraft, Paul Nulsen, Grant Tremblay, and Tom Gauron PLAN: ----- Execute CAP 1617: HRC-I Checkout Activity on Side-A Electronics NOTES/ISSUES/PROBLEMS: ---------------------- No issues of concern were noted during the CAP activity. The HRC team will analyze back orbit telemetry in order to understand heating when various components are turned on and off. Raw data does not indicate any obvious issues with the preamplifiers or processing electronics. CLD Files executed: 2A_PWRUP_SET_135.CLD 2A_IDEFAULTS135.CLD SUMMMARY: -------- The 15V LVPS was successfully powered on, the HRC-I was connected to the side-A preamplifiers, and we collected data at full voltage for 5.4 ks. The HRC was powered down and left in an inactive state at the end of the activity. TIMELINE (GMT day 186): ----------------------- 21:28 OC verifies SCS 87 and SCS 91 as disabled 21:29 SIM focus position is verified 21:29 dither enable is verified 21:32 SCS 135 is enabled and activated, to run command load 2A_PWRUP_SET_135 - sets HVPS steps to 0 and disables motor controls 21:41 +/- 15V LVPS is powered on and verified to run nominally 21:45 24V LVPS is powered on and verified to run nominally 21:46 HRC-I is connected to FEA-A preamplifiers and HRC-I observing defaults are set 21:49 24V LVPS is powered down 21:53 PMT2 brought to operating levels. Shield rates are steady at < 4000 c/s 21:57 HRC-I is powered on and set to 0 steps via SCS 92 21:58 HRC-I HVPS power supply ramp up is initiated 22:01 HRC-I brought to half voltage 22:11 HRC-I is brought to full voltage and collecting data on Cassiopeia A. Rates are as expected. 23:41 SCS 92 was activated, in order to set the HVPS steps to 0 23:42 HRC-I HVPS powered off 23:43 SCS 87 disabled 23:44 PMT2 powered off and steps set to 0 23:45 15V LVPS powered down 23:46 Switch to FMT2 UTC 2022:186:21:20:01 (Jul 5) f_ACE 2.37e+01 F_CRM 0.00e+00 Kp 0.3 R km 87534A OBT 2022:186:21:19:36 CTUVCDU 8368383 OBC s/w NRML FMT1_SSR CPEstat NORM OBT 773443176.90 ONLVCDU 8368376 OBC Errs 0 OBSID 26440 EPState SUN SIM TTpos -50505 HETG Angle 77.96 PCADMODE NMAN RA 294.574 Bus V 28.36 SIM FApos -715 LETG Angle 76.09 PCONTROL NPNT Dec 33.102 Bus I 19.80 AOFSTAR GUID Roll 176.463 ACA Object SSSSSSSS Dither ENAB HRC-I HV OFF ACA ImFunc NNRNRNRR Dith Yang 7.24 Yaw Rate -123.08 HRC-S HV OFF ACA CCD Temp -8.8 Dith Zang 6.89 Pitch Rate 231.49 SHLD HV 0.0 ACA Int Time 1.698 Roll Rate -64.82 EVT RT 4334 AOACSTAT OK FSS SunBeta SUN SHLD RT 0 FSS Alfa -7.55 Batt 1 SOC 100.00% Avg HRMA Temp 72.54 FSS Beta -33.88 Batt 2 SOC 100.00% ACIS Stat7-0 67 Avg OBA Temp 64.51 SA Resolv 125.26 Batt 3 SOC 100.00% Cold Rad -123.1 OBA Tavg Fault NFLT SA Sun Pres ILLM Warm Rad -82.0 OBA Trng Fault NFLT +Y SA Amps 10.06 RadMon ENAB HRMA power 0.00 SCS 128 ACT -Y SA Amps 9.48 OBA power 0.00 SCS 129 ACT +Y SA Temp 110.51 SCS 130 ACT -Y SA Temp 110.20 Roll Mom. -16.094 SCS 131 ACT Pitch Mom. 12.803 SCS 132 ACT Ephin Temp 0.0000 UpLCmdAcc 18620 Yaw Mom. 16.608 SCS 133 ACT EIO Temp 0.0000 Cmd Rej A 172 PMTANKP 135.744 SCS 107 INAC EPH temp 161.30 IRU2G2 curr 117.60 M Unload MON IRU2G1 curr 91.20 Roll Bias 1.0335 TSC Move STOP Prop. line 03 131.94 Pitch Bias -3.0945 CTX B PWR 36.69 FA Move MOVE Prop. line 04 107.02 Yaw Bias -1.6754 CTX B Volts 3.54 OTG Move DISA 616 Explanation Current Data: UTC 2022:186:21:20:01 (Jul 5) f_ACE 2.37e+01 F_CRM 0.00e+00 Kp 0.3 R km 87534A Currently scheduled FPSI, OTG : HRC-I NONE Estimated Kp : 0.3 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 2.37e+01 GOES-R P4 flux, in RADMON P4GM units : 0.078 GOES-R P7 flux, in RADMON P41GM units : 0.013 GOES-R E > 2.0 MeV flux (p/cm^2-s-sr) : 102.0 Orbit Start Time : 0.008 Geocentric Distance (km), Orbit Leg : 87425 A CRM Region : 3 (Magnetosphere) External Proton Flux (p/cm^2-s-sr-MeV) : 2.1155e+02 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 0.0000e+00 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 6.3686e+04 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 0.0000e+00
