EVENTS DONE OBSID -------------- ---- ----- AOS, 5 stars, 3 FIDs 1440 14 LOS 1630 Notes from 9 am meeting ----------------------- Ops: normal Mission planning: the next squeegee mode test is tentatively scheduled for Monday, May 1. There was discussion about the perigee maneuvers - the benefits vs. the fuel consumed. Actions were defined to investigate ACIS focal plane temperature near perigee to see whether it actually deviates from -120 during CTI measurements. Also, we will watch to see how much fuel is actually being consumed by the maneuvers. Spacecraft eng'ng: The dropped command during the safe mode test is thought to have been a case of accidentally hitting the return key instead of entering Y(ES). The script should probably react in a fail-safe manner when this kind of error is made. ASCDS: Several QLs. CXC Mgr: there will be a visit by Fred Jansen, XMM Project Scientist, on the afternoon of May 2.

If there is no comment after the entry, it means the image has not yet appeared in the book. I did a longterm look yesterday because of the uneven flow of QL data lately.
