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 24-26: No fully or partly Earth directed CME observed.

The MAY3104 load products will be out this morning with a review planned for this afternoon. This is the first load replacement with OFLS 10.3, and it went well, with some minor issues. S/C: The IFOT system handled a load replacement successfully, with some fixes applied along the way. We had a momentum dump; it went fine. Thee will be a CPE uplink CAP review tomorrow, and one for the ACIS flight software early next week.
