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 3-5: No fully or partly Earth directed CME observed.
