Bulletin

Solar activity is low, without C-class flares reported during last 24 hours. No significant changes of solar activity are foreseen in the coming hours. The isolated C-class flares are possible but not very probable. No Earth directed CMEs were observed in the last 24 hours.

The Earth is presently inside the slow solar wind with the speed of about 320 km/s. The interplanetary magnetic field magnitude is about 4nT, and the Bz component of the interplanetary magnetic field is fluctuating with values down to -4 nT. The increase of the solar wind speed is possible in the coming hours, due to the late arrival of the fast flow associated with the low latitude extension of the northern polar coronal hole which reached central meridian in the morning of January 12. The equatorial coronal hole with the elongated extension towards the south has crossed central meridian this morning. The associated fast solar wind might arrive at the Earth late on January 18 or in the morning of January 19. The geomagnetic conditions are presently quiet and we expect them to stay so in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 024, gebaseerd op 10 stations.
