Bulletin

Solar activity was low, no C-class flares in past 24 h. There is one new active region that emerged in the eastern hemisphere, it has beta magnetic field configuration and is not expected to produce significant flares in the coming hours.

Proton flux levels are at background values and are expected to remain so. No Earth-directed CMEs were observed.

Solar wind speed is at 375 km/s with interplanetary magnetic field magnitude of 7 nT. Geomagnetic conditions have been quiet. Isolated active periods are possible today, due to the probable arrival of moderately fast solar wind streams associated with a negative polarity diffuse equatorial coronal hole.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 012, gebaseerd op 05 stations.
