Bulletin

Flaring activity was low for the past 24 hours, the strongest event being a B9.3 flare occurring in NOAA AR 1768 on June 13, 1006 UT peak time. A partial halo CME was observed on the same day around 0400 UT on LASCO, but observations indicate a backside event. Finally, a polar crown filament, in the southern hemisphere partially erupted on June 13, around 1200UT; coronagraphic observations of the event are not yet available. We foresee eruptive conditions for the next 48 hours, with a risk of a C flare from NOAA AR 1768. We currently have very quiet geomagnetic conditions. It is expected that this situation will prevail in the next 48 hours.

Today's estimated international sunspot number (ISN): 039, based on 14 stations.
