Performing a series of observations of SNR1006 with ACIS-I. Soft proton levels are somewhat elevated (about 1500). Large increases from this level are not expected. Solar Terrestrial Activity Report: Forecast A small coronal hole (CH30) in the southern hemisphere was in a geoeffective position on April 5. Another and large coronal hole (CH31) in the southern hemisphere will be in a geoeffective position on April 6-9. CH31 is the western part of a huge recurrent coronal hole, the eastern part is rotating into view. The northeastern part of CH31 is trans equatorial. The geomagnetic field is expected to be quiet to active, possibly with minor storm intervals, on April 8 due to effects from the CME impact observed early in the day and a high speed stream from CH30. Unsettled to major storm conditions are possible on April 9-13 when the high speed stream from CH31 dominates the solar wind. Long distance medium wave (AM) band propagation along east-west paths over high and upper middle latitudes is very poor, propagation along north-south paths is poor. [Trans Atlantic propagation conditions are currently monitored every night on 1470 kHz. Dominant station tonight: Radio Cristal del Uruguay.] Seq # ObsID It Target start time SI Grat RA dec roll ------------------------------------------------------------------------------------------------------- APR0703B: 600320 03946 0 NGC 1831 2003:097:23:16:43.168 25.4 ACIS-S NONE 76.5510 -64.8985 240.04 500317 03838 0 SN1006 2003:098:06:50:55.428 20.3 ACIS-I NONE 226.0371 -41.9204 43.00 500317 04385 0 SN1006 2003:098:12:37:25.428 20.3 ACIS-I NONE 225.9746 -42.0913 43.00 500317 04386 0 SN1006 2003:098:18:23:55.428 20.3 ACIS-I NONE 225.7661 -42.1913 43.00 500317 04387 0 SN1006 2003:099:00:10:25.428 20.3 ACIS-I NONE 225.5245 -42.1496 43.00 500317 04388 0 SN1006 2003:099:05:56:55.428 20.3 ACIS-I NONE 225.3911 -42.0079 43.00 ORBITAL EVENTS: 2003:097:15:36:00.988 506 EPERIGEE ORBIT PERIGEE 2003:097:20:01:09.733 507 XE1RADZ0 ELECTRON1 RADIATION EXIT0 2003:098:23:19:53.838 507 EAPOGEE ORBIT APOGEE 2003:100:06:55:23.811 507 EE1RADZ0 ELECTRON1 RADIATION ENTRY0 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 098:1100 AOS DSS-24 (Goldstone 34m) 098:1315 Status at AOS was as expected (see note 1) 098:1330 4385 LOS DSS-24 098:1415 End of shift 098:1415 NOTES/ISSUES/PROBLEMS --------------------- 1) Status at AOS: UTC 2003:098:13:30:06 (Apr 8) f_ACE 1.38e+03 F_CRM 3.44e+08 Kp 4.7 R km 122172A OBT 2003:098:13:29:47 CTUVCDU 350707 OBC s/w NRML FMT2_SSR CPEstat NORM OBT 166195787.56 ONLVCDU 350696 OBC Errs 0 OBSID 4385 EPState SUN SIM TTpos 92903 HETG Angle 79.46 PCADMODE NPNT RA 225.977 Bus V 29.93 SIM FApos -535 LETG Angle 77.96 PCONTROL NPNT Dec -42.090 Bus I 28.74 AOFSTAR GUID Roll 42.999 ACA Object FFFSSSSS Dither ENAB HRC-I HV OFF ACA ImFunc TTTTTTTT Dith Yang 7.67 Yaw Rate -0.22 HRC-S HV ON ACA CCD Temp -10.4 Dith Zang 0.47 Pitch Rate 0.03 OBSMode NEXT ACA Int Time 1.698 Roll Rate 0.12 Door OP UNAC AOACSTAT OK FSS SunBeta SUN Door CL UNAC FSS Alfa 1.26 Batt 1 SOC 100.00% Avg HRMA Temp 70.58 FSS Beta -46.89 Batt 2 SOC 100.00% ACIS Stat7-0 64 Avg OBA Temp 51.05 SA Resolv 136.84 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 99.80 SCS 128 ACT -Y SA Amps 14.49 EPHIN Geom LARG OBA power 51.70 SCS 129 ACT +Y SA Temp 113.28 E150 200.5 SCS 130 ACT -Y SA Temp 113.89 E300 3.0 Roll Mom. 17.728 SCS 107 INAC E1300 0.0 Pitch Mom. 10.814 UpL Cmd Acc 58158 EPH A-Leak 1.0200 P4GM 2.5 Yaw Mom. -16.732 Cmd Rej A 239 EPH B-Leak 0.5760 P41GM 0.0 Explanation Current Data: UTC 2003:098:13:30:06 (Apr 8) f_ACE 1.38e+03 F_CRM 3.44e+08 Kp 4.7 R km 122172A Currently scheduled FPSI, OTG : ACIS-I NONE Estimated Kp : 4.67 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 1.38e+03 GOES-8 P2 flux, in RADMON P4GM units : 0.01 GOES-10 P2 flux, in RADMON P4GM units : 0.01 GOES-8 P5 flux, in RADMON P41GM units : 0.01 GOES-10 P5 flux, in RADMON P41GM units : 0.01 Orbit Start Time : 2003:097:15:39:00 Geocentric Distance (km), Orbit Leg : 122140 A CRM Region : 2 (Magnetosheath) External Proton Flux (p/cm^2-s-sr-MeV) : 6.45294000000e+03 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 6.45294000000e+03 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 5.96481270000e+08 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 3.43678812300e+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 = 3300 ACIS FP Temp = -119.7 DEA Pwr = 48.9 DPA Pwr = 40.3 Science State = Science Active 2) Notes from 9:00am meeting: Operations (Darell): - 2 supports last 24 hours, 1 34m, 1 26m - 1 LS uplinked, active thru 101:1425 - VCDU rollover yesterday - CAP 563A, CPE warm start count run yesterday, count was same as before(1) - Dumps current Mission Planning (Ken): - APR14 products will be out this morning for a load review this afternoon. S/C Engineering(Richard, Sabina): - Gyro current problem: * Current on Gyro A, IRU1 still stabilized at about 150ma, toggeling between 148 and 151 ma. * IRU swap procedure still being worked on * Telecon yesterday with Kearfott. They suggested re-commanding the IRU on as a diagnostic. In other missions this procedure has lowered the current level, but only temporarily.
