Bulletin

Solar activity was moderate during the last 24 hours. A C1 flare took place in NOAA AR 1771, close to the East limb on June 15, peaking at 0400 UT. It was a long duration event linked to a CME as witness by SDO/AIA observations (there is a data gap in LASCO observations). There is no risk of geomagnetic consequences. We expect at most isolated C flares from the following ARs: AR 1768, AR 1769, and to a lesser extent AR 1772, 1770 and 1771. We expect essentially quiet geomagnetic conditions for the next 48 hours.

Today's estimated international sunspot number (ISN): 066, based on 08 stations.
