ACIS SOT Shift report L2985 Sep 23, 2007 07:00 EDT,2007:266:11:00 GMT COMM Period: = 2007 Sep 23 07:00 am EDT End = 2007 Sep 23 08:00 am EDT See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html or /proj/web-cxc/htdocs/acis/SOT_reports/Sep_23_2007_L2985_acis.txt ACIS Personnel: Joseph DePasquale, Paul Plucinsky PLAN: ---- We will evaluate ACIS thermal telemetry to verify that the side B detector housing heater was turned back on. The commands to do so were contained in the SEP2407 command load and should have turned the heater back on at 266:07:30 GMT. We will have the contingency CAP 1042 ready to go if needed. SUMMARY: ------- At 0705 EDT, the ACIS team was able to verify that the heater had been turned back on, as expected in the load, and that the camera body temperature had warmed back up to -59.9 C on the B side, and -62.4 C on the A side. The detector housing side B heater current and voltage were consistent with the heater having turned back on and regulating at -59.9 C. The telemetry seen was: 1DAHTBEN=EN 1DAHTBON=ON 1DAHHBVO= 28.98 (value of the mean over 10 samples) 1DAHBVO= 6.85 (value of the mean over 10 samples) 1DAHBCU= 0.50 (value of the mean over 10 samples) 1CBBT= -59.9 (value of the mean over 10 samples) 1CBAT= -62.4 (value of the mean over 10 samples) Snapshot at AOS: UTC 2007:266:11:02:06 (Sep23) f_ACE 2.22e+01 F_CRM 2.75e+09 Kp 3.7 R km 124878A OBT 2007:266:11:01:31 CTUVCDU 12696191 OBC s/w NRML FMT2_NORM CPEstat NORM OBT 306932491.90 ONLVCDU 12696176 OBC Errs 0 OBSID 7523 EPState SUN SIM TTpos 75624 HETG Angle 79.09 PCADMODE NPNT RA 175.961 Bus V 29.77 SIM FApos -467 LETG Angle 77.21 PCONTROL NPNT Dec -61.133 Bus I 28.24 AOFSTAR GUID Roll 175.492 ACA Object FFFSSSSS Dither ENAB HRC-I HV OFF ACA ImFunc TTTTTTTT Dith Yang -5.75 Yaw Rate -0.31 HRC-S HV ON ACA CCD Temp -19.6 Dith Zang 4.67 Pitch Rate -0.07 SHLD HV 8.0 ACA Int Time 1.698 Roll Rate -0.30 EVT RT 0 AOACSTAT OK FSS SunBeta SUN SHLD RT 21 FSS Alfa -0.33 Batt 1 SOC 100.00% Avg HRMA Temp 70.63 FSS Beta 28.52 Batt 2 SOC 100.00% ACIS Stat7-0 64 Avg OBA Temp 54.39 SA Resolv 61.31 Batt 3 SOC 100.00% Cold Rad -127.9 OBA Tavg Fault NFLT SA Sun Pres ILLM Warm Rad -82.0 OBA Trng Fault NFLT +Y SA Amps 13.91 RadMon ENAB HRMA power 0.00 SCS 128 INAC -Y SA Amps 14.10 EPHIN Geom SMAL OBA power 16.60 SCS 129 ACT +Y SA Temp 112.66 E150 53.4 SCS 130 ACT -Y SA Temp 113.58 E300 5.4 Roll Mom. 15.046 SCS 107 INAC E1300 8.5 Pitch Mom. 6.791 UpL Cmd Acc 3246 EPH A-Leak 1.0200 P4GM 0.0 Yaw Mom. 6.668 Cmd Rej A 213 EPH B-Leak 0.0000 P41GM 0.0 EPH temp 107.86 Gyro 2 Curr 1 103.20 Roll Bias -0.9807 EPH 27I 7.82 M Unload MON Gyro 2 Curr 2 98.40 Pitch Bias -2.0473 TSC Move STOP Prop. line 03 104.49 Yaw Bias -1.1822 CTX A PWR 36.54 FA Move STOP Prop. line 04 71.31 CTX A Volts 3.50 OTG Move DISA Explanation Current Data: UTC 2007:266:11:02:06 (Sep23) f_ACE 2.22e+01 F_CRM 2.75e+09 Kp 3.7 R km 124878A Currently scheduled FPSI, OTG : ACIS-S NONE Estimated Kp : 3.67 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 1.74e+01 GOES-10 P2 flux, in RADMON P4GM units : 0.00 GOES-12 P2 flux, in RADMON P4GM units : 0.00 GOES-10 P5 flux, in RADMON P41GM units : 0.02 GOES-12 P5 flux, in RADMON P41GM units : 0.03 Orbit Start Time : 2007:265:12:19:00 Geocentric Distance (km), Orbit Leg : 124762 A CRM Region : 1 (Solar_Wind) External Proton Flux (p/cm^2-s-sr-MeV) : 1.74000000000e+01 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 1.74000000000e+01 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 8.01816198900e+09 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 2.75109039900e+09 Snapshot at LOS: UTC 2007:266:12:00:05 (Sep23) f_ACE 2.05e+01 F_CRM 2.75e+09 Kp 1.7 R km 126465A OBT 2007:266:11:58:55 CTUVCDU 12709631 OBC s/w NRML FMT1_NORM CPEstat NORM OBT 306935935.91 ONLVCDU 12709616 OBC Errs 0 OBSID 7586 EPState SUN SIM TTpos -99616 HETG Angle 79.09 PCADMODE NMAN RA 206.180 Bus V 29.77 SIM FApos -990 LETG Angle 4.09 PCONTROL NPNT Dec -58.074 Bus I 27.98 AOFSTAR GUID Roll 209.411 ACA Object FFFSSSSS Dither ENAB HRC-I HV OFF ACA ImFunc RRRNNRNN Dith Yang 3.45 Yaw Rate -211.42 HRC-S HV ON ACA CCD Temp -19.6 Dith Zang 7.95 Pitch Rate -5.08 SHLD HV 8.0 ACA Int Time 1.698 Roll Rate 104.96 EVT RT 0 AOACSTAT OK FSS SunBeta SUN SHLD RT 21 FSS Alfa 0.40 Batt 1 SOC 100.00% Avg HRMA Temp 70.63 FSS Beta 28.07 Batt 2 SOC 100.00% ACIS Stat7-0 66 Avg OBA Temp 54.62 SA Resolv 61.65 Batt 3 SOC 100.00% Cold Rad -127.9 OBA Tavg Fault NFLT SA Sun Pres ILLM Warm Rad -82.0 OBA Trng Fault NFLT +Y SA Amps 13.72 RadMon ENAB HRMA power 34.50 SCS 128 ACT -Y SA Amps 13.91 EPHIN Geom SMAL OBA power 35.10 SCS 129 ACT +Y SA Temp 112.97 E150 76.2 SCS 130 ACT -Y SA Temp 113.58 E300 5.0 Roll Mom. 13.656 SCS 107 INAC E1300 5.5 Pitch Mom. 11.488 UpL Cmd Acc 6302 EPH A-Leak 1.0200 P4GM 0.0 Yaw Mom. 4.421 Cmd Rej A 252 EPH B-Leak 0.0000 P41GM 0.0 EPH temp 112.31 Gyro 2 Curr 1 103.20 Roll Bias -0.9810 EPH 27V 9.52 M Unload MON Gyro 2 Curr 2 98.40 Pitch Bias -2.0472 TSC Move STOP Prop. line 03 110.25 Yaw Bias -1.1819 CTX A PWR 36.43 FA Move STOP Prop. line 04 71.31 CTX A Volts 3.52 OTG Move DISA Explanation Current Data: UTC 2007:266:12:00:05 (Sep23) f_ACE 2.05e+01 F_CRM 2.75e+09 Kp 1.7 R km 126465A Currently scheduled FPSI, OTG : HRC-S LETG Estimated Kp : 1.67 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 1.74e+01 GOES-10 P2 flux, in RADMON P4GM units : 0.00 GOES-12 P2 flux, in RADMON P4GM units : 0.00 GOES-10 P5 flux, in RADMON P41GM units : 0.02 GOES-12 P5 flux, in RADMON P41GM units : 0.03 Orbit Start Time : 2007:265:12:19:00 Geocentric Distance (km), Orbit Leg : 126412 A CRM Region : 1 (Solar_Wind) External Proton Flux (p/cm^2-s-sr-MeV) : 1.74000000000e+01 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 0.00000000000e+00 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 8.01822462900e+09 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 2.75114259900e+09
