Shift L2268. Start at 279:13:00 GMT = 08:00am 06 Oct EDT End 10:00am 06 Oct SOT Lead DAS (Times will be given in GMT on day 279.) PLAN ---- Continue running load OCT0305C. Do obsid 6213, part of the Extended Groth strip survey by ACIS-I. Then do obsid 7176, an ACIS-S/HETG observation of the high mass-accretion rate (Mdot) nonmagnetic cataclysmic variable star TT Ari to study the X-ray plasma and contrain the boundary layer parameters. No Comm this shift.

EPH temp 87.33 degF NOTES/ISSUES/PROBLEMS ACIS is running 1.5 deg warm. From the 9am status meeting: Three supports over the past 24 hours. We had issues with the front end processor string over three supports. Problems at the JPL CDR caused delay of data. Problem is resolved, but data is backed up and expected to take several hours to catch up. No Chandra data lost, and we did not roll over to SSR-B. One segment of OCT0305C was uplinked: on-board loads are good until 282:16:11. Products for OCT1005 expected out this morning for a 1pm load review. (If products are delayed the load review may be later.) Sun is expected to be very quite over the next few days. ACE soft protons are at their background level. The HEAD email will be down for about an hour starting at noon today. Also, HEAD computers will be off the air for some time for re-boot. This is expected to ease the email delays experienced over the past many weeks. Flight Director's CCB this afternoon at 2pm. Will hear the closeout for the stuck heater 50 on the optical bench. Design review 3-5pm today for the Prop Line temperature monitor patch.
