Bülletään

During last 24 hours solar activity was very low with no C-class and even B-class flares reported. As there are no numbered active regions observed on the visible side of the solar disc, we expect such a low flaring activity to persist in the coming hours. The coronagraph images do not show any signatures of the possibly Earth- directed CME. The solar proton flux is at the background level.

The Earth is presently inside the slow solar wind with the speed of about 320 km, and the interplanetary magnetic field magnitude is about 3 nT. The geomagnetic conditions are quiet and we expect them to remain so in the coming hours. The unsettled geomagnetic conditions can be expected starting from the late evening of January 22, 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.
