Solar activity is gradually increasing. From 20 till 23 February, there was 1 CME each day. Only the first one had an earth-directed component, the other CMEs were clearly directed away from Earth or farside events.

Space Weather is 'in' and more and more organisations want to learn about it. They are right to do so.
Solar storms drop their energy in the Earth's magnetosphere and atmosphere and as such lie at the basis of space weather. Technology that relies on satellite navigation and radio wave propagation can be impacted by space weather, as well as large energy transport systems like electrical grids. Harmful radiation at flight altitude can increase when a solar storm hits Earth.

Last week, in response to the high speed solar wind stream associated with a coronal hole, the level of energetic electrons in the Earth's magnetosphere increased significantly. Fortunately, this time, these "killer electrons" did not permanently phase out a satellite.
