Shift L546. Start at 018:13:00 GMT = 08:00am 18 Jan EST End 12:00 noon 18 Jan SOT Lead DAS (Times will be given in GMT on day 018. In general times are rough, not precise.) PLAN ---- Continue running load JAN1601b. Complete CTI measurement at perigee egress, and do OBSID 2186, ACIS-S/LETG observations of H1821+643, for the entire orbit. Next Comms: 018:15:00 to 16:00 019:00:00 to 01:00 019:09:00 to 10:00 019:19:00 to 20:00 Orbital events: 2001:018:10:45:34.804 200 ORBIT PERIGEE 2001:019:18:29:36.318 201 ORBIT APOGEE 2001:021:02:13:54.067 201 ORBIT PERIGEE EVENTS ------ Status at LOS, 018:06:58, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 8 FIDS = 0 RA = 349.996 deg Dec = 45.000 deg ROLL = 313.429 deg Format = 2 OBSID = 61770 ACIS CTI SIM FA = -467 SIM TSC = -99616 (HRC-S) HETG = OUT (79.84 deg) LETG = IN ( 4.46 deg) HRC-S HV is ON EPHIN Geom = LARG E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.5 LT 300.

Triggers) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 0.2280 mu-a Ascending through 52943 km. ACIS focal plane temperature -119.9. 15:58 LOS Status essentially unchanged. Ascending through 60331 km. ACIS focal plane temperature -119.9 NOTES/ISSUES/PROBLEMS SOT area EGSE machines were disconnected from real time data flow following a switch from squirt1 to squirt2. ACA and HRC have been restarted, ACIS team still needs to restart their telemetry receive process. Simulation exercise has diagnosed a gyro failure. Meeting at 10am outlined actions to be taken. Team will reconvene at 3pm to report on actions. Debrief will follow exercise, probably at 5pm. The phone line 305-503-1818 passcode 421 will be used. From the 9am status meeting: Three supports in last 24 hours, all data recovered, on-board loads good until 022:07:50. JAN2201d load still needs signoffs, will happen today. JAN2901 is progressing. Venus observations had about a 90 arcsec offset between OFLS and a hand-calculation. This was not a problem, but should be discussed among Wolk, Grimes, Davis, and Shropshire. GOT will use telemetry and command servers on string 1 for about an hour today, for checkout and training of new personnel. Meet in action room at 10am to resume simulation. ACIS operations meeting 10am tomorrow, 6th floor conference room. Meeting on star selection parameters, 10am - 2 or 3pm tomorrow, OCC conference room. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 1897 SS CYG 016:21:27 HRC-S LETG Looks good. ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 877-693-7198 PIN 693-7198 or e-mail 6937198@archwireless.net -------------------------------------------------------
