Bulletin

Solar flaring activity became moderate, with several C flares and recently an M1.2 flare peaking at 10:54 UT from the new region that has rotated onto the disc in the north-east. The region is numbered NOAA active region 3030 and appears as bipolar but is currently still too close to the limb to allow more detailed analysis. Some spot formation is recorded in the northern hemisphere but it remains to be seen if this persists. C flares are expected with also a possibility for M-class flaring.

The northward CME reported yesterday was assessed to not reach Earth. A filament eruption from the southeastern quadrant yesterday afternoon resulted in a CME towards the South-East which is too narrow to affect Earth. No other Earth directed CMEs have been recorded in coronagraph data.

The greater than 10 MeV proton flux was at background levels and is expected to remain so. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold. The 24h electron fluence was at normal levels and is expected to be at low to normal levels.

Slow solar wind conditions were recorded with solar wind speed around 300 km/s. The interplanetary magnetic field reached to 8.5nT with the Bz component not below -6nT. The phi angle indicated connection with a negative sector (field away from the Sun) until recently. Slow solar wind conditions are expected over the next days.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-2, local K Belgium 0-3). Quiet geomagnetic conditions are expected over the next days.

Today's estimated international sunspot number (ISN): 054, based on 16 stations.
