Telecon convened to discuss the situation. The exact reason for the dither being disabled is not yet known. Dither was re-enabled by CAP (one command), and correct dither was verified. Emails to be sent by RAC to explicitly notify USINT and DSops of this situation Obsids 3832 (3C58), 4106 (F04103-2838), 04384 (PSR B1509-58), and half of 3837 (TYCHO'S SNR) were done without dither. - Soft proton rates are low again after a spike yesterday - ACIS FP temperature -119.9 C Snapshot -------- Snapshot does NOT match expected configuration: UTC 2003:119:21:40:04 (Apr29) f_ACE 3.70e+01 F_CRM 3.51e+08 Kp 3.3 R km 128670A OBT 2003:119:21:39:34 CTUVCDU 7545983 OBC s/w NRML FMT2_SSR CPEstat NORM OBT 168039574.58 ONLVCDU 7545968 OBC Errs 0 OBSID 3837 EPState SUN SIM TTpos 92903 HETG Angle 79.46 PCADMODE NPNT RA 6.315 Bus V 30.55 SIM FApos -535 LETG Angle 77.96 PCONTROL NPNT Dec 64.112 Bus I 22.63 AOFSTAR GUID Roll 36.363 ACA Object FFFSSSSS Dither DISA HRC-I HV OFF ACA ImFunc TTTTTTTT Dith Yang 0.00 Yaw Rate -0.04 HRC-S HV ON ACA CCD Temp -10.8 Dith Zang 0.00 Pitch Rate -0.34 OBSMode NEXT ACA Int Time 1.698 Roll Rate 0.11 Door OP UNAC AOACSTAT OK FSS SunBeta SUN Door CL UNAC FSS Alfa 0.74 Batt 1 SOC 100.00% Avg HRMA Temp 70.63 FSS Beta 35.85 Batt 2 SOC 100.00% ACIS Stat7-0 64 Avg OBA Temp 51.37 SA Resolv 54.00 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 11.02 RadMon ENAB HRMA power 67.30 SCS 128 ACT -Y SA Amps 11.41 EPHIN Geom LARG OBA power 59.30 SCS 129 INAC +Y SA Temp 111.12 E150 6.0 SCS 130 ACT -Y SA Temp 111.74 E300 0.2 Roll Mom. -7.587 SCS 107 INAC E1300 0.0 Pitch Mom. 5.275 UpL Cmd Acc 24039 EPH A-Leak 1.0200 P4GM 0.1 Yaw Mom. 5.003 Cmd Rej A 22 EPH B-Leak 0.4760 P41GM 0.0 Gyro 1 Curr 1 148.80 Gyro 1 Curr 2 98.40 Gyro 2 Curr 1 9.60 Gyro 2 Curr 2 9.60 Explanation Current Data: UTC 2003:119:21:40:04 (Apr29) f_ACE 3.70e+01 F_CRM 3.51e+08 Kp 3.3 R km 128670A Currently scheduled FPSI, OTG : ACIS-I NONE Estimated Kp : 3.00 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 3.70e+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 : 0.01 GOES-12 P5 flux, in RADMON P41GM units : 0.01 Orbit Start Time : 2003:118:19:19:01 Geocentric Distance (km), Orbit Leg : 128637 A CRM Region : 3 (Magnetosphere) External Proton Flux (p/cm^2-s-sr-MeV) : 4.28198000000e+03 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 4.28198000000e+03 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 6.60264548400e+08 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 3.51078863400e+08
