Bulletin

Only minor C-class flaring from NOAA AR 3089 (beta-delta magnetic field configuration) was recorded in the last 24 hours. This AR has potential for M-class flares, so they remain possible but not very likely. C-class flares can be expected.

No earth directed CMEs were detected in the past 24 hours.

The greater than 10 MeV proton flux is below the 10 pfu mark, and is expected to remain so. The greater than 2MeV electron flux was below the 1000 pfu threshold over the past 24 hours. It is expected to remain below threshold over the next 24 hours. The 24h electron fluence was at nominal levels over the past 24 hours. It is expected to remain at nominal levels over the next 24 hours.

The solar wind speed has decreased to around 420 km/s with interplanetary magnetic field magnitude around 5 nT. Continuing slow solar wind conditions are expected for the next 24 hours.

Quiet geomagnetic conditions were recorded over the past 24 hours (NOAA Kp and K_Dourbes up to 2). Similar conditions can be expected for the next 24 hours.

Today's estimated international sunspot number (ISN): 060, based on 22 stations.
