Bulletin

The only C-class flare of the past 24 hours (C1.9 peaking at 07:02 UT today) occurred above the north-east solar limb, seemingly produced by the still unnumbered sunspot group that just appeared from behind the east limb (returning NOAA AR 2342). More C-class flares are expected from this active region. A partial halo CME originating in this active region was detected by SOHO/LASCO on June 1. It first appeared in the LASCO C2 field of view at 13:48 UT and had the angular width of around 200 degrees. SDO/AIA observations of associated coronal dimmings and an EIT wave demonstrate that the CME originated from behind the north-east solar limb, so it will not arrive at the Earth and will have no geomagnetic consequences. The Earth is currently inside a slow (around 340 km/s) solar wind flow with slightly elevated (around 6 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Today's estimated international sunspot number (ISN): 034, based on 11 stations.
