Shift L1958. Start at 335:13:00 GMT = 08:00am 30 Nov EST End 10:00am 30 Nov SOT Lead DAS (Times will be given in GMT on day 335.) PLAN ---- Continue running load NOV2904B. Currently in radiation belts. Will do an ascending CTI measurement, then obsid 5774, an ACIS-I observation of the high-redshift cluster of galaxies cl0809+2811, to measure the gas masses in a systematic ROSAT sample at redshift z>0.35. Then obsid 4522, an ACIS-S cc-mode observation of the candidate double-degenerate binary RX J1914.4+2456 to monitor its orbital evolution. Then obsid 6150 resumes the ACIS-S/HETG study of pre-eclipse dips in HER X-1. No Comm this shift.

DEC0604 products expected out later today, for initial load review tomorrow. DNS issues being worked. Some processes are very sluggish. Trying to get spare parts for the sparc 20. No engineering issues. No science instrument issues. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 5119--5122 HRC-S calibrations on AR Lac.
