Geomagnetic activity is expected to gradually increase over the next 48 hours in response to the anticipated arrival of another coronal hole. Solar Activity Forecast: Solar activity is expected to be low, with isolated chance of M-class flares. Current soft proton rates from ACE are low, EPHIN rates on-board are very low. (2) Notes from 9:00am meeting: Operations (Ken): - 1 SCS loaded - Loads active to day 195 at 0450 - Waiting for last SSR playback during current comm - 4 supports scheduled over 24 hours Mission Planning (Ken): - JUL1403B products reviewed, changes to prepare for IRU swap being put in place - Email review for JUL1403C today S/C Engineering(Dan): - Several limit trips yesterday and the day before - ACA CCD temp below limit: After ACA cooldown, temp went slightly lower than expected. This is most likely an issue with ACA cal curve. - PEA power supply temp tripped for 30 sec, got to 103.1 degrees, limit 103. Needs investigation - Gyro currents settling a little, about 150 ma - GRETA promotion today, swap-over TBD SOT(Tom): - See above radiation report DSOPS(Joy) - Quicklooks: SN1987A, Bades window GOT/IST(Chris): - Building AC on 24/7 now - OFLS1 processor swap went smoothly Meetings/events: - 9:15am: IST tagup - 1pm: contractor telecon 1pm - 4pm: CSC telecon - 3-6pm: Ball telecon on 305-503-1818 Quicklooks ---------- 3830 SN1987A ACIS-S NONE OK 3780 Bade's Window ACIS-I NONE OK Snapshot -------- Chandra snapshot matches predicted configuration: TC 2003:191:12:53:03 (Jul10) f_ACE 3.74e+01 F_CRM 8.70e+08 Kp 1.7 R km 130390D OBT 2003:191:12:52:38 CTUVCDU 14921676 OBC s/w NRML FMT2_PCAD CPEstat NORM OBT 174228758.81 ONLVCDU 14921664 OBC Errs 0 OBSID 3780 EPState SUN SIM TTpos 92903 HETG Angle 79.46 PCADMODE NPNT RA 270.791 Bus V 30.08 SIM FApos -535 LETG Angle 77.59 PCONTROL NPNT Dec -29.947 Bus I 34.31 AOFSTAR GUID Roll 291.742 ACA Object FFFSSSSS Dither ENAB HRC-I HV ON ACA ImFunc TTTTTTTT Dith Yang -6.02 Yaw Rate 0.00 HRC-S HV OFF ACA CCD Temp -15.6 Dith Zang 7.96 Pitch Rate 0.17 OBSMode NEXT ACA Int Time 1.698 Roll Rate 0.10 Door OP UNAC AOACSTAT OK FSS SunBeta NSUN Door CL UNAC FSS Alfa -49.57 Batt 1 SOC 100.00% Avg HRMA Temp 70.58 FSS Beta -49.78 Batt 2 SOC 100.00% ACIS Stat7-0 65 Avg OBA Temp 51.21 SA Resolv 162.71 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 18.02 RadMon ENAB HRMA power 95.60 SCS 128 ACT -Y SA Amps 18.41 EPHIN Geom LARG OBA power 70.20 SCS 129 ACT +Y SA Temp 107.90 E150 0.9 SCS 130 ACT -Y SA Temp 108.17 E300 0.1 Roll Mom. -0.559 SCS 107 INAC E1300 0.0 Pitch Mom. -10.879 UpL Cmd Acc 2019 EPH A-Leak 0.4480 P4GM 0.0 Yaw Mom. 4.168 Cmd Rej A 252 EPH B-Leak 0.0880 P41GM 0.0 Gyro 1 Curr 1 156.00 Gyro 1 Curr 2 100.80 Gyro 2 Curr 1 96.00 Gyro 2 Curr 2 98.40 Explanation Current Data: UTC 2003:191:12:53:03 (Jul10) f_ACE 3.74e+01 F_CRM 8.70e+08 Kp 1.7 R km 130390D Currently scheduled FPSI, OTG : ACIS-I NONE Estimated Kp : 1.67 ACE EPAM P3 Proton Flux (p/cm^2-s-sr-MeV) : 3.26e+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 : 0.02 Orbit Start Time : 2003:190:04:59:00 Geocentric Distance (km), Orbit Leg : 130393 D CRM Region : 3 (Magnetosphere) External Proton Flux (p/cm^2-s-sr-MeV) : 3.38170000000e+02 Attenuated Proton Flux (p/cm^2-s-sr-MeV) : 3.38170000000e+02 External Proton Orbital Fluence (p/cm^2-sr-MeV) : 9.87113700144e+09 Attenuated Proton Orbital Fluence (p/cm^2-sr-MeV) : 8.69915431440e+08
