Shift L1155. Start at 262:12:00 GMT = 08:00am 19 Sep EDT End 12:00 noon 19 Sep SOT Lead DAS (Times will be given in GMT on day 262.) PLAN ---- Continue running load SEP1602C. Do obsid's 4372 and 4371, ACIS-S observations of the S0 galaxy NGC 1332 to measure the shape of the dark matter halo, and NGC1600, an X-ray-bright elliptical to study the interaction between the X-ray emitting gas and cooler interstellar material.

ACIS focal plane temperature -119.7 14:40 LOS Comm was extended a few minutes to complete playback. Status is essentially unchanged. Ascending through 123099 km. ACIS focal plane temperature -119.7 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Two supports: Canberra stowed its 34m antenna due to high winds, so support was shifted to a 24m station. There were initial receiver lock problems with DSS 24 but this was resolved and support was extended 25 minutes to recover all data. On board loads are good until 266:11:01. SEP2302C loads were approved yesterday. OFLS 9.4 is being installed, benchmarks are completed and FOT/MP expects to be running on it later today. Keith Havey is visiting from EKC, working with Rino for a couple of days.
