Complete observations of SN1006 (obsid 4394) with ACIS-I and then start observation of NGC 5746 (obsid 3929) with ACIS-S. Soft proton levels have continued to decrease, flux under 300 at 1130 GMT. Solar activity is expected to be low over the next few days. Geomagnetic activity is expected to be unsettled to minor storm, when the high speed stream from CH31 dominates the solar wind, Seq # ObsID It Target start time SI Grat RA dec roll ------------------------------------------------------------------------------------------------------- APR0703B: 500317 04392 0 SN1006 2003:100:20:50:01.182 20.1 ACIS-I NONE 225.8079 -41.9163 43.00 500317 04393 0 SN1006 2003:101:02:33:05.182 20.1 ACIS-I NONE 225.6329 -41.9496 43.00 500317 04394 0 SN1006 2003:101:08:16:09.182 20.1 ACIS-I NONE 225.7286 -42.0371 43.00 600303 P2 03929 0 NGC 5746 2003:101:14:25:03.230 37.1 ACIS-I NONE 221.2554 1.9446 115.61 700770 P2 04091 0 SDSS J143030.22-0011 2003:102:01:12:00.230 2.0 ACIS-S NONE 217.6716 -0.1314 115.78 ORBITAL EVENTS: 2003:100:07:04:40.197 507 EPERIGEE ORBIT PERIGEE 2003:100:11:53:23.811 508 XE1RADZ0 ELECTRON1 RADIATION EXIT0 2003:101:14:48:03.132 508 EAPOGEE ORBIT APOGEE 2003:102:15:33:59.077 508 EE1RADZ0 ELECTRON1 RADIATION ENTRY0 2003:102:22:32:26.915 508 EPERIGEE ORBIT PERIGEE 2003:103:02:11:59.077 509 XE1RADZ0 ELECTRON1 RADIATION EXIT0 2003:104:06:15:43.181 509 EAPOGEE ORBIT APOGEE EVENTS DONE OBSID -------------- ---- ----- Start Shift 101:1100 AOS DSS-24 (Goldstone 34m) 101:1200 Status at start shift was as expected (see note 1) 101:1200 LOS DSS-24 101:1300 End of shift 101:1400 NOTES/ISSUES/PROBLEMS --------------------- 1) Status at AOS: UTC 2003:101:12:11:04 (Apr11) f_ACE 2.57e+02 F_CRM 6.18e+08 Kp 3.3 R km 130707A OBT 2003:101:12:10:39 CTUVCDU 1343689 OBC s/w NRML FMT2_SSR CPEstat NORM OBT 166450239.75 ONLVCDU 1343680 OBC Errs 0 OBSID 4394 EPState SUN SIM TTpos 92903 HETG Angle 79.46 PCADMODE NPNT RA 225.727 Bus V 29.93 SIM FApos -535 LETG Angle 77.96 PCONTROL NPNT Dec -42.039 Bus I 32.03 AOFSTAR GUID Roll 42.996 ACA Object FFFSSSSS Dither ENAB HRC-I HV OFF ACA ImFunc TTTTTTTT Dith Yang -7.64 Yaw Rate -0.12 HRC-S HV ON ACA CCD Temp -10.4 Dith Zang 2.08 Pitch Rate -0.03 OBSMode NEXT ACA Int Time 1.698 Roll Rate -0.11 Door OP UNAC AOACSTAT OK FSS SunBeta SUN Door CL UNAC FSS Alfa -1.60 Batt 1 SOC 100.00% Avg HRMA Temp 70.61 FSS Beta -49.37 Batt 2 SOC 100.00% ACIS Stat7-0 64 Avg OBA Temp 51.05 SA Resolv 139.21 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 15.85 RadMon ENAB HRMA power 42.30 SCS 128 ACT -Y SA Amps 16.05 EPHIN Geom LARG OBA power 67.40 SCS 129 ACT +Y SA Temp 112.97 E150 27.4 SCS 130 ACT -Y SA Temp 114.20 E300 0.3 Roll Mom. 16.019 SCS 107 INAC E1300 0.0 Pitch Mom. -13.623 UpL Cmd Acc 61477 EPH A-Leak 1.0200 P4GM 0.0 Yaw Mom. -13.159 Cmd Rej A 89 EPH B-Leak 0.3400 P41GM 0.0 Explanation Current Data: UTC 2003:101:12:11:04 (Apr11) f_ACE 2.57e+02 F_CRM 6.18e+08 Kp 3.3 R km 130707A Currently scheduled FPSI, OTG : ACIS-I NONE Estimated Kp : 3.33 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 2.57e+02 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 : 2003:100:07:09:00 Geocentric Distance (km), Orbit Leg : 130690 A CRM Region : 2 (Magnetosheath) External Proton Flux (p/cm^2-s-sr-MeV) : 2.22561000000e+03 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 2.22561000000e+03 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 4.23225300900e+09 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 6.17571423000e+08 HRC IM PS = OFF SP PS = ON Stps 43/54 Shield 1 HV = OFF Shield 2 HV = ON Stp 7 Valid Event Rate 1 = 0 Valid Event Rate 2 = 0 Shield Event Rates = 3000 ACIS FP Temp = -119.5 DEA Pwr = 44.0 DPA Pwr = 39.7 Science State = Science Active 2) Notes from 9:00am meeting: Operations (Darell): - 3 supports last 24 hours, 2 34m, 1 26m - 0 LS uplinked, still active thru 104:0021 - In DSS-66 pass at 101/0100-0200 we were not able to get any dump data due to station problems. Swapped to legacy equipment, and still were not able to get dump. - In this morning's DSS-24 pass we were able to catch up on dump data. - Dumps now current Mission Planning (Ken): - TOO proposed but required observation time is still pending. Would be observed either in the middle of next week or beginning of following week. Time to be established today, approval likely. - Work on APR21 loads on hold pending resolution of TOO. S/C Engineering(Sabina, Rino, Eric): - Gyro current noise increased again, topped 170ma for a time Performance remains unaffected. - Were not able to test run IRU swap procedure on ASVT yesterday due to ASVT problems. - ASVT problems have been fixed, will test procedure today. - Are working towards an IRU swap as soon as products and procedures are verified. - Target next Tuesday for a final run-thru test of the swap procedure. SOT(Bill): - See above notes on radiation DSOPS(Joy) - Two new SN1006 QL's (see below) GOT/IST(Mike/Chris): - All OK Meetings/events: - 9:15am, IST daily tagup - 1:00pm, Ball SMF move meeting 3) Quick look data: Seq # ObsID It Target start time SI Grat Comment ---------------------------------------------------------------------------------------------------- 500317 04385 0 SN1006 2003:098:12:37:25.428 20.3 ACIS-I NONE 500317 04391 0 SN1006 2003:100:15:06:57.182 20.1 ACIS-I NONE
