Bulletin

There are 2 visible active regions on the solar disk, both with alpha magnetic field configuration. No C-class flares or higher in the past 24 hours. Solar activity is expected to be low in the next 24 hours.

A CME erupted at 10:36 UT on 22 January (angular width about 90 degrees), it was directed mostly towards the norteas, but it could have an Earth directed component, with expected arrival on 26 January.

A coronal hole (positive polarity) crossed the central meridian on 21 January, its associated high speed steam can be expected at the Earth in about 48 hours.

The greater than 10 MeV proton is below the 10 pfu threshold. The greater than 2 MeV electron flux is slightly above the 1000 pfu alert threshold and is expected to remain close to the threshold during the next 24 hours. The 24h electron fluence was at moderate levels and is expected to remain so in the next 24 hours.

The solar wind speed at Earth is about 400 km/s, and the interplanetary magnetic field around 5 nT. Slow solar wind conditions are expected for the next 24 hours.

Geomagnetic conditions were quiet to unsettled locally (K_Bel 1 - 3) and at planetary levels (Kp 2 - 3). The CME from 20 January may arrive to the Earth in the next 24 hours, increasing geomagnetic conditions to active or even minor storm levels.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 021, gebaseerd op 05 stations.
