Finishing obsid 7229, an ACIS-S/HETG observation of the normal O-star HD93129AB as part of a characterization of the O-star H-R diagram. Then obsid 6820, an ACIS-S GTO observation of the optically luminous quasar SDSS J0209-0005. Then into perigee passage. No comm this shift.

EPH temp 96.12 degF EPH 27V 26.84 NOTES/ISSUES/PROBLEMS From the 9am status meeting: One support in the last 24 hours. No issues. DEC0505B was reviewed, corrected C products were issued, reviewed, and have been approved for uplink. Two large M-class solar flares early today may lead to CME hitting earth late this weekend. There is a large, active sunspot group. Meeting at 10am EST to discuss updated EPHIN thermal prediction model, and discuss operational strategy for controlling EPHIN temperature. Follow on discussion may include changes to mission planning guidelines in regard to how long we may point in various pitch zones, and the minimum duration into which observations may be split.
