PLAN ---- Continue running load JUL2300. Finish OBSID 914, ACIS-I observation of the cluster of galaxies CL J0542.8-4100. Then make CTI measurements surrounding perigee number 134. Next Comms: 209:17:45 to 18:45 210:04:00 to 05:00 210:14:35 to 15:35 210:20:45 to 22:45 211:04:35 to 05:35 211:11:30 to 13:25 211:20:40 to 22:40 212:06:30 to 07:30 212:14:45 to 15:45 212:20:50 to 22:50 Orbital events 2000:209:21:54:58.851 134 ORBIT PERIGEE 2000:211:05:40:00.422 135 ORBIT APOGEE 2000:212:13:25:18.690 135 ORBIT PERIGEE EVENTS ------ Status at LOS, 209:08:43, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 85.739 deg DEC = -40.988 deg ROLL = 139.281 deg Format = 2 OBSID = 914 CL J0542.8-4100 SIM FA = -535 SIM TSC = 92903 (ACIS-I) HETG = OUT (80.2 deg) LETG = OUT (78.3 deg) HRC-I HV is ON EPHIN Geom = LARG E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.3 LT 300.

NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: 2 Supports, 3 SSR dumps, all successful. Last segment of load JUL2300 was uplinked, on-board loads good through 213:04:06. First review of JUL3000 took place. New products out this morning for a review at 1pm today. Changes were adding star catalogs, the proper dither for HRC observations, and momentum dump. Testing of OFLS 9.0 is proceeding on schedule. MP testing of ephemeris and attitude expected to be completed soon. ONLS testing will proceed on a new patch for the command system, but awaits new disk drive hardware. Expected completion may be around mid-August. ASVT testing of the LETG scripts failed yesterday. Nested loops caused a problem, will be rebuilt with GO TO statements. Products for the solar array off-point demo to be tested the rest of this week. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 00736 G347.5-0.5 207:14:44 ACIS-I Looks good 00737 G347.5-0.5 207:23:32 ACIS-I Looks good (These are two different pointing positions at a large remnant.) ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 800-759-8352 PIN 1636502 or e-mail 1636502@skytel.com -------------------------------------------------------
