ACIS Shift report L386 Aug 12 6:15 EDT, GMT 225:10:15 PLAN: Execute CAP 640B to run the subarray Squeegy test. SUMMARY: The ACIS focal plane was warmer than expected at the beginning of the pass. So, we decided to skip the non-Squeegy control run at the end of the CAP is use the entire for the subarray Squeegy test. The subarray Squeegy quick-look results show that the FWHM is comparable to the "maximum angular resolution" squeegy flavor. Radiation Environment: ACE 130-214 keV proton flux had decreased to 2,000 particles/cm2-s-ster-MeV at the beginning of the pass but had spiked up to 10,000 briefly during the pass. At the end of the pass the rates had dropped to 7,500. The KP index was at 8.0, this is higher than I have ever seen it. GOES rates were flat. EPHIN rates were quite low. The SIM is at the HRC-S position for the belt transit so we are safe for the nect 9 hr. We have a long COM tonight for the LETG retraction. We should be prepared for the possibility that the radiation environment will get worse and terminating the load at that pass. SIM moves ACIS into focus at 226:01:12 GMT. 1) Detailed Timeline: GMT 225:10:15 AOS on DSS 24 225:10:16 FP temp = -117.4 C 225:10:17 EPHIN rates E150=4.6, E300=0.1, E1300=0.0, P4GM=0.0 cts/s cm^2 sr altitude 82,000 km and descending E1300, P4, and P41 are all a factor of three below our safing criteria 225:10:25 OC starts uplinking the loads 225:10:38 OC start executing commands in step 3 of CAP640B 225:10:40 FP temp = -117.9 C 225:10:46 we lose command capability from OPS4, Cambridge Ops investigates 225:10:49 FP temp = -118.3 C 225:10:51 switch to OP3 while Cambridge Ops continues diagnosis 225:10:54 commands complete except for stopScience, pause at step 14 of the CAP 225:10:56 FP temp = -118.4 C E150=14.4, E300=0.2, E1300=0.0, P4GM=0.0 cts/s cm^2 sr 225:11:02 FP temp = -118.6 C 225:11:20 FP temp = -118.9 C 225:11:25 FP temp = -119.1 C 225:11:26 startScience 225:11:28 FP temp = -119.2 C 225:11:33 first bias packets 225:11:34 last bias packets 225:11:35 first event data 225:11:40 FP temp = -119.4 C 225:11:52 FP temp = -119.5 C 225:11:59 FP temp = -119.7 C 225:12:12 FP temp = -119.9 C 225:12:41 E150=198, E300=3.6, E1300=0.1, P4GM=0.4 cts/s cm^2 s altitude 67,000 km and descending 225:12:47 confirm stopScience from the daily load 225:12:48 dump PRAM 225:12:49 dump SRAM 225:12:51 confirm radiation belt entry commands from daily load 225:12:52 E150=23707, E300=84, E1300=0.1, P4GM=28.3 cts/s cm^2 s 225:13:00 SCS slots cleared 225:13:05 uplinked 2D window block which the OFLS is expecting to be already stored in ACIS 225:13:20 LOS 2) Chandra state at the beginning of the pass: UTC 2000:225:10:18:01 (Aug12) f_ACE 8.51e+03 F_ACE 2.13e+09 Kp 7.3 R km 83389D OBT 2000:225:10:17:38 CTUVCDU 9131620 OBC s/w NRML FMT2_NORM CPEstat OBT 82462658.74 ONLVCDU 9131608 OBC Errs 0 OBSID 61968 EPState SUN SIM TTpos -99616 HETG Angle 80.2 PCADMODE NMAN RA 335.485 Bus V 30.55 SIM FApos -467 LETG Angle 4.5 PCONTROL NPNT Dec -43.391 Bus I 31.78 AOFSTAR GUID Roll 29.461 ACA Object SSSSSSSS Dither ENAB HRC-I HV ON ACA ImFunc NNNNNRNN Dith Yang 1.83 Yaw Rate -25.61 HRC-S HV OFF ACA CCD Temp -10.4 Dith Zang 6.49 Pitch Rate 210.53 OBSMode NEXT ACA Int Time 1.698 Roll Rate 10.94 Door OP UNAC AOACSTAT OK FSS SunBeta NSUN Door CL UNAC FSS Alfa -42.54 Batt 1 SOC 100.00% Avg HRMA Temp 70.61 FSS Beta -49.75 Batt 2 SOC 100.00% ACIS Stat7-0 66 Avg OBA Temp 50.26 SA Resolv 151.11 Batt 3 SOC 100.00% Cold Rad -125.5 OBA Tavg Fault NFLT SA Sun Pres ILLM Warm Rad -82.0 OBA Trng Fault NFLT +Y SA Amps 15.46 HRMA power 9.60 SCS 128 -Y SA Amps 15.85 EPHIN Geom LARG OBA power 100.30 SCS 129 +Y SA Temp 108.97 E150 4.6 SCS 130 -Y SA Temp 109.58 E300 0.1 Roll Mom. 5.575 E1300 0.0 Pitch Mom. -10.025 UpL Cmd Acc 35555 EPH A-Leak 0.1520 P4GM 0.0 Yaw Mom. -0.760 Cmd Rej A 124 EPH B-Leak 0.0280 P41GM 0.0 3) Chandra state at the end of the pass UTC 2000:225:13:20:02 (Aug12) f_ACE 1.87e+03 F_ACE 0.00e+00 Kp 7.3 R km 62900D OBT 2000:225:13:19:14 CTUVCDU 9174143 OBC s/w NRML FMT2_EPS CPEstat OBT 82473554.95 ONLVCDU 9174128 OBC Errs 0 OBSID 61968 EPState SUN SIM TTpos -99616 HETG Angle 80.2 PCADMODE NPNT RA 176.849 Bus V 30.87 SIM FApos -467 LETG Angle 4.5 PCONTROL NPNT Dec -44.362 Bus I 31.27 AOFSTAR GUID Roll 216.459 ACA Object SSSSSSSS Dither ENAB HRC-I HV ON ACA ImFunc TTTTTNNN Dith Yang 6.19 Yaw Rate 0.06 HRC-S HV OFF ACA CCD Temp -10.4 Dith Zang -2.48 Pitch Rate -0.11 OBSMode NEXT ACA Int Time 1.698 Roll Rate -0.12 Door OP UNAC AOACSTAT OK FSS SunBeta SUN Door CL UNAC FSS Alfa -0.39 Batt 1 SOC 100.00% Avg HRMA Temp 70.61 FSS Beta 22.85 Batt 2 SOC 100.00% ACIS Stat7-0 67 Avg OBA Temp 50.50 SA Resolv 66.99 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 14.88 HRMA power 61.40 SCS 128 -Y SA Amps 16.05 EPHIN Geom LARG OBA power 133.90 SCS 129 +Y SA Temp 108.17 E150 97.1 SCS 130 -Y SA Temp 108.44 E300 2.6 Roll Mom. 3.573 E1300 0.0 Pitch Mom. -2.381 UpL Cmd Acc 38471 EPH A-Leak 0.1840 P4GM 0.3 Yaw Mom. 4.444 Cmd Rej A 205 EPH B-Leak 0.0360 P41GM 0.0 SOT LEAD: ACIS: Paul Plucinsky, Catherine Grant, Mark Bautz, Royce Buehler
