No C class events were recorded yesterday. (http://www.dxlc.com/solar/) CMEs reported for past two days: August 22-24: No obviously Earth directed CMEs were detected in LASCO images.

S/C: - GOT/IST: DATA: SOT: The EPHIN E1300 flux was at about 1/2 the threshold during the last snapshot(see above. and below), and for a few minutes previous. There was an event like that yesterday from 17-22h, as well, also in protons, but not showing in ACE. That event was from the rad zone. Today's event occurred outside the rad zone. We'll have to collect more data to understand it better. Goes X-ray flux - Quiet the past two days. Today, one minor barely C class short duration event.
