EVENTS DONE OBSID -------------- ---- ----- 3 fids, 4 stars 1544 964 3 fids, 5 stars 1642 57 LOS 1645 Notes from 9 am meeting ----------------------- Ops: 3 supports, load good till day 065. Mission planning: The new OFLS8.0 is working well so far. On the first run of MAR1200, OFLS8 did good things. It did an unlinked run; the previous version couldn't. It handled fixed durations observations with very little dead time. On the other hand, a request for a TOO was rejected because of concern about disrupting operations during initial operation with the new OFLS. FOT SI: Eric reports several major solar flares. ACE electrons increased several times in the past day, but low energy protons show nothing. The 130-214 keV flux is <100. Spacecraft eng'ng: plan to uplink a CAP for medium eclipse patches tomorrow afternoon. Data: On colossus (/dsops/GOT/input), Mar 3 10:22 2000_062_2254_063_0723_Dump_EM_29032.gz Ground systems: completed failover testing today on aommand, tlm, SMACK. Still need to do database servers. SOT Mgr: informed ASCDS that the OBSID 964 observation has a potential aspect problem because the HRC door was moved some time between 062:23:52 and 23:02 GMT. Evaluation of QL data --------------------- The following observations from the last ten days should be available for review. If there is no comment after the entry, it means the image has not yet appeared in the book.

Also, HRC expressed a concern that the door may flop about now that it's no longer pushed against the snubber, and may affect aspect.
