PLAN ---- Continue running load NOV2000c. Do the Hubble deep field north, OBSID 1671, using ACIS-I, for this entire orbit. remaining science observations for the week are as follows: ObsID Target start time SI Grat ------------------------------------------------------------------- 2344 HDF NORTH 329:06:03 92 ACIS-I NONE 88 CEN X-3 330:08:20 40 ACIS-I NONE 1996 CRAB NEBULA 330:20:27 28.5 ACIS-S NONE Coord with HST 2041 KI 284 331:20:15 10.0 ACIS-S NONE 1854 M31 TRANSIENT TBD 332:00:05 5.0 ACIS-S NONE Next Comms: 328:01:45 to 02:45 328:08:00 to 09:00 328:18:00 to 19:00 329:01:15 to 02:05 329:08:15 to 09:15 329:18:00 to 19:00 330:03:00 to 04:00 330:10:15 to 11:15 330:21:00 to 22:00 331:04:15 to 05:15 331:13:40 to 14:40 331:22:15 to 23:15 Orbital events: 2000:327:14:06:27.088 179 ORBIT APOGEE 2000:328:21:49:52.836 179 ORBIT PERIGEE 2000:331:13:17:18.216 180 ORBIT PERIGEE EVENTS ------ Status at LOS, 327:08:57, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 189.246 deg DEC = 62.190 deg ROLL = 44.310 deg Format = 2 OBSID = 1671 HDF-N SIM FA = -535 SIM TSC = 92903 (ACIS-I) HETG = OUT (79.84 deg) LETG = OUT (78.34 deg) HRC-S HV is ON EPHIN Geom = LARG E1300 = 0.1 LT 10.0 (RADMON P4GM = 0.8 LT 300.

Rob reports on the ACA dark current tests: "I have processed all 5 SFDU files, and there are no data gaps in the ACA cal data." "I have median filtered the ACA cal data and reconstructed images of the ACA focal plane, for 5 and 10 second exposures. The median filter seems to work quite well. The images can be seen in /proj/telmon/tlm/raw/cal/2000326/ image5.fits image10.fits Note: these are preliminary data." From the 9am status meeting: Uplinked 1 more load segment, on-board loads good until 330:21:00. However, we expect to replace that with the NOV2000d load. The NOV2000d products are out, review at 11am this morning. This revision moves the start time of the Cen X-3 OBSID 88 back to 300:08:20:37.051, giving it 40 Ksec. This is at the expense of the HDF-N OBSID 2344, however that time will be added to next February's cycle somewhere in the OBSID 2232-2234 series. This is all ACIS GTO time, which will be reduced the corresponding 20Ksec for cycle 3. This load was approved at the 11am review. Revised products for Nov2700b have also been circulated, and a load review is planned for 2pm this afternoon.
