Shift L2210. Start at 221:13:00 GMT = 08:00am 09 Aug EDT End 10:00am 09 Aug SOT Lead DAS (Times will be given in GMT on day 221.) PLAN ---- Continue running load AUG0805C. Do obsid 6265, an ACIS-S/HETG spectrum of the Classical T Tauri Star V4046 Sgr, to distinguish between accretion and coronal X-ray emission. Then obsid 5387, an ACIS-S observation of the star HD 184905, as part of a survey of B/A stars with strong magnetic fields. Then obsid 5404, continuing the ACIS-I observation of young stellar objects in the Coronet Cluster and coordinated with the VLA in order to monitor for coincident X-ray and radio flares.

Hope to approve and signoff today. ACIS is running a little warm, at -118.9 deg C. ACE solar protons at background level. No significant solar activity is expected. The SGI TLM2 server is back on line. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 5423 V4046 Sgr 218:20:11 ACIS-S HETG Good.
