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.
