SOT Shift Report 2005-01-20 L2009 Duration: 20 Jan 2005 08:00 EST - 20 Jan 2005 10:00 EST 20 Jan 2005 13:00 GMT - 20 Jan 2005 15:00 GMT SOT Lead: Tom Aldcroft ======================================== Plan ---- No load running; develop products for upcoming eclipse Events ------ 13:05 AOS on DSS-54 14:05 LOS Notes from 9am meeting ---------------------- Summary of 8am Go/No-go telecon: - Due to the X7.9 flare at 020:0639 and associated very strong hard proton event, radiation rates are much too high to start the JAN2005A load Ops: In Radiation Zone NO Current SI Grating NONE Observation ID None, Finished 59843 Target None, Finished CTI Altitude 105.6 kkm Asc Radmon Disable 365/23:59z Next Radiation Zone Event not available yet. MP: - Next eclipse at 022:1416, so in the absense of the JAN2005 load, a maneuver/eclipse-only load will be developed. Expect products out today and review tomorrow. - Most likely plan is to attempt to resume science coming out of the next perigee after the comm at 022:2230-2330. Eng: - Went through eclipse #4 and it appears to have been nominal Radiation: - X7.9 flare from region 720 starting at 020:0639 with an associated very fast and strong proton event. This is the strongest flare this year. - Latest EPHIN rates from the 1305-1405 pass were quite high: E1300 242.9 P4GM 655.8 P41GM 41.1 - Soft proton rate from ACE P3 channel is currently moderately high (~5000) and declining steadily Snapshot -------- Snapshot matches expected configuration: UTC 2005:020:14:07:04 (Jan20) f_ACE 5.88e+03 F_CRM 0.00e+00 Kp 1.0 R km 112015A OBT 2005:020:14:03:58 CTUVCDU 2427391 OBC s/w NRML FMT2_NORM CPEstat NORM OBT 222617038.52 ONLVCDU 2427376 OBC Errs 0 OBSID 59843 EPState SUN SIM TTpos -99616 HETG Angle 79.09 PCADMODE NPNT RA 112.500 Bus V 28.99 SIM FApos -467 LETG Angle 77.59 PCONTROL NPNT Dec 3.699 Bus I 36.85 AOFSTAR GUID Roll 331.050 ACA Object SSSSSSSS Dither ENAB HRC-I HV ON ACA ImFunc TTTTTTTT Dith Yang 1.47 Yaw Rate -0.03 HRC-S HV OFF ACA CCD Temp -15.6 Dith Zang 3.10 Pitch Rate 0.05 SHLD HV 0.0 ACA Int Time 1.698 Roll Rate -0.13 EVT RATE 255 AOACSTAT OK FSS SunBeta NSUN SHLD RATE 255 FSS Alfa -31.73 Batt 1 SOC 100.00% Avg HRMA Temp 70.61 FSS Beta -49.77 Batt 2 SOC 100.00% ACIS Stat7-0 66 Avg OBA Temp 51.13 SA Resolv 161.17 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 18.60 RadMon DISA HRMA power 73.80 SCS 128 INAC -Y SA Amps 18.21 EPHIN Geom SMAL OBA power 78.70 SCS 129 INAC +Y SA Temp 116.95 E150 48780.5 SCS 130 INAC -Y SA Temp 118.05 E300 1550.5 Roll Mom. 5.036 SCS 107 DISA E1300 242.9 Pitch Mom. -13.040 UpL Cmd Acc 4086 EPH A-Leak 0.8200 P4GM 655.8 Yaw Mom. 6.543 Cmd Rej A 23 EPH B-Leak 0.1600 P41GM 41.1 EPH temp 52.13 Gyro 1 Curr 1 9.60 Roll Bias -0.8232 EPH 27I 6.59 M Unload MON Gyro 1 Curr 2 9.60 Pitch Bias -2.0000 TSC Move STOP Gyro 2 Curr 1 103.20 Yaw Bias -1.1011 CTX B PWR 36.73 FA Move STOP Gyro 2 Curr 2 100.80 CTX B Volts 3.54 OTG Move DISA Explanation Current Data: UTC 2005:020:14:43:01 (Jan20) f_ACE 5.10e+03 F_CRM 0.00e+00 Kp 0.7 R km 113363A Currently scheduled FPSI, OTG : HRC-S NONE Estimated Kp : 1.00 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 5.10e+03 GOES-10 P2 flux, in RADMON P4GM units : 0.64 GOES-12 P2 flux, in RADMON P4GM units : 1.45 GOES-10 P5 flux, in RADMON P41GM units : 6.06 GOES-12 P5 flux, in RADMON P41GM units : 8.18 Orbit Start Time : 2005:019:18:49:01 Geocentric Distance (km), Orbit Leg : 113213 A CRM Region : 3 (Magnetosphere) External Proton Flux (p/cm^2-s-sr-MeV) : 2.72566300000e+03 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 0.00000000000e+00 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 2.82920308038e+10 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 0.00000000000e+00
