Shift L206. Start at 045:13:00 GMT = 08:00am 14 Feb EST End 12:00 noon 14 Feb SOT Lead DAS Spac/Aspect FOT/Sci liason HRC ACIS (Times will be given in GMT on day 045. In general times are rough, not precise.) PLAN Continue running load FEB1300c. Finish observing Coma cluster with HRC-I (OBSID 562). Observe V382 Velorum, a TOO novae in outburst, using HRC-S/LETG (OBSID 958). Perform CTI measurements before and after belt passage surrounding the perigee at 045:23.

On-board Chandra loads will run through 049:10:30. FOT/MPS will start FEB2000 load -- plan for review no later than Thursday. A meeting to discuss the star selection process has previously been set up for Wed pm, with thursday, and friday morning available as needed for extra time. Rob and Tom and appropriate SOT/MPS should attend. Meetings postponed due to the solar activity actions are to be re-scheduled: for detailed setup of an observation, and for discussion of radiation zone configurations. The FOT/MPS has accepted an action item to investigate scheduling slews INSIDE the 13000Ksec pad time on the radiation zone transfers. The current problem is that SIM and grating moves must be made prior to RADMON disable, and the OFLS schedules these moves during slews. 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.
