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

All eyes to the north tonight 👀 A Coronal... Mass Ejection is forecast to arrive on earth, potentially giving opportunities to see the Northern Lights. Strong auroral activity is possible in northern Scotland, but even southern England could catch a glimpse in any cloud breaks.show more

A Coronal Mass Ejection (CME) is expected to arrive... today, giving increased geomagnetic activity and potential Aurora sightings 🤩 The best chance of seeing the lights will be across Scotland where skies are clear and the Aurora is strongestshow more

A SOLAR TSUNAMI: We are expecting wave after wave... of coronal mass ejections to striking the Earth on 11th and 12th May. Solar wind speeds of about 800 km/s are possible. Strong and extended geomagnetic storms likely with aurora visible at lower-than-normal latitudes. Stay tuned.show more

Some of us could end Boxing Day with a... glistening sky display ✨ The aurora may be enhanced tonight due to a coronal hole high speed stream and a coronal mass ejection Northern Scotland, plus perhaps central and southern Scotland, may see the aurora in any clear intervalsshow more

👀 You may see the northern lights this evening... and overnight due to a Coronal Mass Ejection Despite it's imminent arrival there's considerable uncertainty and it may only glance Earth. If it arrives, aurora could be spotted as far south as northern England if skies are clear.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
