Start at 049:13:00 GMT = 08:00am 18 Feb EST End 10:00am 18 Feb SOT Lead DAS (Times will be given in GMT on day 049.) PLAN ---- Continue running load FEB1311A. Finish obsid 12955, an ACIS-S observation of the galaxy NGC4342 in the Virgo cluster, to study the ram pressure stripping in its X-ray corona. Then into perigee passage. NOTES/ISSUES/PROBLEMS --------------------- HETG retracted position has returned to the reading of 79.09. Suspicion is that it is just toggling near a bit boundary. From the 9am status meeting: Three supports over the past day. No issues. First stored command sequence of FEB2111A was uplinked, on-board loads are good until 052:20:56. ACE soft protons peaked near a flux of 90,000 last night, triggering a radiation telecon. However rates quickly decreased so there was no need to shut down. This radiation was from the CME associated with the X2 flare on day 015.
