Major far side eruption, S1 radiation storm
The minor S1 solar radiation storm threshold was reached this evening. This is unfortunately not the result of a front side eruption but a major far side eruption behind the west limb. The Sun's magnetic field or Parker Spiral which wraps around the solar system carries the protons from the far side all the way to the Earth and beyond.
