Bulletin

Solar activity has been very low, no C-class flares in past 24 h. NOAA AR 2612 remains the only visible AR, it has alpha magnetic field configuration. Solar activity is expected to remain low, but C-class flares are possible.

Proton levels are low and there were no Earth directed CMEs in past 24 h. Solar wind speed is at 640 km/s with interplanetary magnetic field intensity of 7 nT. The Earth is still inside a high speed stream from a coronal hole. Due to solar wind speeds above 700 km/s and magnetic field intensities reaching 12 nT with extended periods of negative Bz, geomagnetic conditions have reached minor storm levels overnight at Dourbes (and major storm at planetary levels). Similar conditions can be expected for the next 48 h.

Today's estimated international sunspot number (ISN): 014, based on 13 stations.
