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.
A lot of people come to SpaceWeatherLive to follow the Solar activity or if there is a chance to see the aurora, but with more traffic comes higher costs to keep the servers online.
