Bulletin

During last 24 hours there were no C-class flares reported. New and still not numbered active region, which started to emerged yesterday morning, became more complex and it was source of A-class flares and one B-class flare this morning. We expect such a low flaring activity to persist in the coming hours. Isolated low C-class flares are possible but not very probable. There were no Earth directed CMEs reported during last 24 hours and the solar protons remained at the background level.

The Earth is still inside the slow solar wind with the speed of about 310 km. The interplanetary magnetic field magnitude is presently about 4 nT. The geomagnetic conditions are quiet and we expect them to remain so in the coming hours. The unsettled to active geomagnetic conditions can be expected starting from the late evening today, due to expected arrival of the fast solar wind from the extended positive polarity equatorial coronal hole which reached central meridian in the morning of January 19.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 017, gebaseerd op 15 stations.
