Shift L1723. Start at 100:12:00 GMT = 08:00am 09 Apr EDT End 10:00am 09 Apr SOT Lead DAS (Times will be given in GMT on day 100.) PLAN ---- Continue running load APR0504B. Measure ACIS CTI ascending from perigee, then do a series of ACIS-S calibrations on E0102, obsids's 5130, 5132, 5133, 5134. Next Comms: 100:1915 to 2015 101:0230 to 0330 101:1115 to 1215 101:1945 to 2045 102:0345 to 0445 102 1300 to 1400 102:2200 to 0000 103:0300 to 0400 103:1040 to 1240 103:1900 to 2100 Orbital events: 2004:100:04:53:35.354 645 EPERIGEE ORBIT PERIGEE 2004:101:12:36:45.319 646 EAPOGEE ORBIT APOGEE 2004:102:20:20:43.885 646 EPERIGEE ORBIT PERIGEE 2004:104:04:04:19.238 647 EAPOGEE ORBIT APOGEE 2004:105:11:47:38.926 647 EPERIGEE ORBIT PERIGEE 2004:106:19:31:57.031 648 EAPOGEE ORBIT APOGEE 2004:108:03:15:11.014 648 EPERIGEE ORBIT PERIGEE 2004:109:10:59:45.590 649 EAPOGEE ORBIT APOGEE EVENTS ------ Status at AOS, 100:10:42, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 8 FIDS = 0 RA = 197.998 deg Dec = -24.001 deg ROLL = 359.340 deg Format = 2 OBSID = 60287 Ascending CTI SIM FA = -467 SIM TSC = -99616 (HRC-S) DITHER = ENAB HETG = IN ( 5.96 deg) LETG = OUT (77.59 deg) HRC-S HV is ON EPHIN Geom = LARG E150 = 4.3 E300 = 0.3 E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.1 LT 300. Disabled) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 0.4120 mu-a Ascending through 59127 km. ACIS focal plane temperature -119.7 C. EPH temp 59.33 F LOS 12:37 Status is essentially unchanged. Ascending through 69733 km. ACIS focal plane temperature -119.7 C. EPH temp 57.17 F NOTES/ISSUES/PROBLEMS ACE soft protons are increasing steeply. At ~8,000 as of 12:00GMT. Presumably due to CME's, which have occured on the 5th, 6th, and 8th. From the 9am status meeting: Three supports in the past 24 hours. No significant issues. First segment of the APR1204A load was uplinked, on-board loads good until 103:21:30. APR1904 products are in work, expected Monday or early Tuesday for a Tuesday load review. Yesterday's Flight Director's CCB approved new planning guidelines for lowering the allowed predicted ephin temperature to 95 F. (We have been operating that way for a couple of weeks.) Also, new MATLAB starcheck tools were approved which fixed the bug that caused the missing fid lights in the HRC-S obsid 5168. The ACIS software patch was approved at Level II for uplink (procedures, scripts, and command loads still need approval). The returned EPS power supply was installed in ASVT and verified to work, so the EPS test set is again functional. REMINDER: Power outage for the NE-80 building, 8-11am EDT tomorrow. If the VPN server is brought back up after power is restored, we anticipate no impact on possible replans and load reviews, in case of a prior radiation shutdown.
