Our active sun continues to disturb Earth’s geomagnetic field. At the time of this writing a G1 (minor) geomagnetic storm is ongoing. The threshold was reached at 9:15 UTC. We saw activity the whole time during our observation period between 11 UTC yesterday and 11 UTC today. Late yesterday and early today we saw another G1 disturbance, during the 0-3 UTC period. People have reported auroral displays in Europe, Canada and the U.S. The G1 storming occurred during the dark hours in the U.S. ...| EarthSky
Sun activity is high this week, so far. There were 7 M flares in the past day. And check out the newcomer on the sun’s eastern, or incoming, side. Remember sunspot region AR3738? It produced an X flare and numerous M and C flares during its trip across the Earth-facing sun from July 5 to 17. Then the sun’s rotation carried it to the far side, where it produced an X14 flare! The flare – and its effects – were observed thanks to the Solar Orbiter spacecraft, which can see the sun’s fa...| EarthSky

Solar radiation storms occur when a large-scale magnetic eruption, often causing a coronal mass ejection and associated solar flare, accelerates charged particles in the solar atmosphere to very high velocities. The most important particles are protons which can get accelerated to large fractions of the speed of light. At these velocities, the protons can traverse the 150 million km from sun to Earth in just 10’s of minutes or less. When they reach Earth, the fast moving protons penetrate t...| www.swpc.noaa.gov
