SOT shift report 2004-05-07 L1751 Written at 2004:128:13:42 UTC = 09:42 AM May-07-2004 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 04851, PKS 2254+074 2004:128:07:16, HRC-I NONE - EXTENDED EMISSION AND ACCRETION RATES IN BL LACERTAE OBJECTS. Then 04733, M101 2004:128:14:00, ACIS-S NONE - 1 Ms observation of M101, a near-by face-on spiral in a direction of low Galactic absorption. Tomorrow morning, we'll watch the momentum unload from the onboard load for the first time since we stopped doing it after the thruster anomaly. RADIATION SUMMARY ----------------- Solar soft proton flux is very low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: The solar flare activity level was very low. No C class events were recorded yesterday. (http://www.dxlc.com/solar/) CMEs reported for past two days: May 4-6: No fully or partly Earth directed CME observed.

The MAY1704A load is in work. S/C: CAP831, momentum dump contingency, was approved yesterday, for possible use tomorrow. There will be an ephemeris update next week. GOT/IST: OFLS 10.3 was approved for promotion at yesterday's FDB. It wil be implemented initially without using the new radiation automation and CRM.
