Bulletin

Solar activity was moderate during the past 24 hours, with one noticeable event, a C1.9 flare, occurring in NOAA AR 1765, on June 10, at 14:24 UT peak time. It was accompanied by a small EUV coronal wave and a metric type II burst. Despite a data gap in coronagraphic data from STEREO and SOHO, around the time of the event, there is a hint around 1554 UT (STEREO COR2 A) of a small narrow CME possibly associated with this flare, but it seems to quickly vanish. NOAA AR 1765 decreased both in terms of sunspot number and area, and maintains a simple beta magnetic configuration. Being the only region on the disk, we expect therefore quiet conditions for flares, with a small chance of a C class event from this region. Geomagnetic activity is expected to be low for the next 48 hours. Current interplanetary conditions, as measured by ACE are quiet.

Today's estimated international sunspot number (ISN): 010, based on 11 stations.
