Bulletin
Solar activity is expected to reach eruptive levels with risks of C class flares from NOAA AR 1708, 1710 and 1711. The past 24 hours were quiet; the only noticeable event being a weak type II radio burst, around 1320UT, linked to a small eruptive event (B4.8) in NOAA AR 1708, with no obvious CME. Geomagnetic activity is expected to be quiet for the next 48 hours.
Today's estimated international sunspot number (ISN): 061, based on 13 stations.
