SOT shift report 2001-06-14 L693 Start at 2001:165:08:30 GMT = 2001 Jun 14 04:30 am EDT End 10:00 am EDT SOT Lead Ed Kellogg, Bill Podgorski Plan: do LETG retraction Also, OBSID 02040, NGC3115 2001:165:10:50, ACIS-S NONE - THE VERY FAINTEST X-RAY FAINT EARLY-TYPE GALAXIES; resolve the LMXBs in these galaxies in order to discover why these galaxies are producing significantly fewer and/or less luminous LMXBs. then OBSID 01563, NGC3923 2001:165:21:37, ACIS-S NONE - determine the density distribution and temperature of the hot gas within this early-type galaxy.

We will start on the JUN25 load next week. We are working on various tests, including star parameters. S/C: Ron Kaichi at TEW West has developed a CSD command tracker to analyze command timing. We have uploaded last week's OTG commands, and will run them on ASVT with the tracker today. GOT: OFLS 9.1b and 9.2a are having difficulty running with ONLS 3.8, so they are not yet fully operational. SOT: We ran CAP 728A this AM to retract the LETG. Radiation is low but rising. There was an M7 flare at 1140 UT Jun13, which may be giving us some protons.
