Bulletin

There is one active region visible on the solar disk, NOAA 2725 with alpha magnetic field configuration. No C-class flares in past 24 h. Solar activity is expected to remain at low levels.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 415 km/s with interplanetary magnetic fields of 3 nT. Geomagnetic conditions have been quiet. The fast solar wind associated with the low latitudinal extension of the northern polar coronal hole (positive polarity) may arrive to the Earth on October 19-20, causing active geomagnetic conditions. Due to its latitude, the high speed stream may pass north of the Earth and leave it unaffected (quiet conditions expected in that case).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 22 stations.
