S2 solar raditation storm, Earth-directed CME

Solar protons reached the moderate S2 threshold today for the second time this solar cycle. Moderate S2 solar radiation storms will cause problems with HF radio communications at polar latitudes and have a minor impact on some types of satellite services, This is all due to the highly eruptive M4.1 solar flare from the west limb which peaked at 15:58 UTC yesterday. This solar flare launched an impressive coronal mass ejection but it is not aimed at Earth.
