Yesterday’s moderately-sized (M8-class) #SolarFlare produced a massive eruption (a... coronal mass ejection), currently en route to Earth. Forecasters have issued a ‘severe’ geomagnetic storm watch (G4 on G1-5 scale). Expect to see misinformation about this, so here are some facts:show more

Earth was hit by multiple CMEs triggering a G3-... geomagnetic storm last night, and we're now being buffeted by fast solar wind. More Earth-directed solar storms are racing towards Earth and are expected to impact in <12 hours now. I expect G3-G4 geomagnetic conditions, get ready!show more

BREAKING – A significant Earth-directed solar flare and associated... coronal mass ejection (CME) just occurred on Friday evening. There is an increasing chance of geomagnetic storms and the potential for a display of the aurora borealis (northern lights) sometime Sunday night into Monday. A "solar flare" is a flash of light and radiation flickering into space. They emanate from sunspots – bruise-like discolorations on the surface of the sun that throb and pulsate with energy. That just occurred associated with sunspot #4100. The flare was a magnitude M8.2; M is one step below X, the highest category. An M8.2 is very close to X-class status. It was followed by a "full halo CME", or coronal mass ejection. That's an explosion of magnetism and solar material that surfs a shockwave through space. We call it a "full halo" because – when it's pointed directly at Earth – it looks like a halo. When CMEs, or coronal mass ejections, arrive at Earth, the electromagnetic energy is absorbed and dissipated by Earth's magnetic field. That energy is transformed into visible light – the aurora. I'll have updates once more information becomes available.show more
