A negative polarity trans-equatorial coronal hole is visible on the Sun and will connect to Earth with its magnetic field and high-speed solar wind in ~5-6 days. The last geoeffective coronal hole high-speed-stream impact we had perfectly lined up with the Venezuela earthquake doublet (M7.2 & M7.2) and the...

🚨 PARKER SOLAR PROBE JUST FOUND HIGH-ENERGY PARTICLES NEAR THE SUN THAT NO MODEL PREDICTED AND WE DON’T KNOW HOW THEY GOT SO ENERGETIC. During its close passes through the solar corona, NASA’s Parker Solar Probe detected protons accelerated to energies around 400 keV roughly 1,000 times higher than current models of magnetic reconnection at the heliospheric current sheet could explain. The particles appear to be trapped and energized inside magnetic islands that form and merge during reconnection events at the current sheet (the vast surface where the Sun’s magnetic field flips polarity). This mechanism was not expected to produce such high energies so close to the Sun. Why this matters: • It reveals a previously unknown or underestimated source of energetic particles right in the solar corona • Existing models of solar energetic particles have focused mainly on shocks from coronal mass ejections — this suggests reconnection can also be a powerful accelerator • The same process may be contributing more to coronal heating than previously calculated • It has implications for space weather forecasting, since these particles can affect spacecraft and astronauts The deeper implication: Parker is showing us that the physics of the near-Sun environment is more energetic and complex than our models assumed. Magnetic reconnection long known as an important process appears capable of accelerating particles to surprisingly high energies through the merging of magnetic islands. This doesn’t just tweak our understanding of the Sun; it may force revisions in how we model particle acceleration across many astrophysical environments. We’re still in the early stages of understanding what Parker is revealing, but it’s already clear that the corona is more violent and dynamic than we thought. How do you think this discovery might change our models of space weather or solar physics in the coming years? Follow for more updates from Parker Solar Probe and the evolving picture of our Sun.

*SEVERE geomagnetic storm possible with U.S. aurora borealis display* *Northern lights possible at mid-latitudes early Sunday morning or Sunday night* *Specifics TBD – map coming later today* On Friday evening Eastern time, a major solar flare occurred from sunspot #4100. A sunspot is a bruise-like discoloration on the sun that throbs and pulsates with energy. Following the solar flare, which is a flash of light and radiation, a significant CME — or coronal mass ejection — was hurled directly toward Earth. Imagine a shockwave of magnetism and high-energy particles rippling through space like an interstellar tsunami. It’s heading for us at speeds around 1,200 miles per second — that’s very fast! We know it’s Earth-directed because our sensors indicate a “full halo” CME. See the solar material appearing to fan out in all directions? That’s an indicator it’s Earth-bound. It’s like if a train is coming right at you — you’d only see the train getting bigger. Once this electromagnetic shockwave reaches Earth, the energy will be absorbed and dissipated by our magnetic field. It will be transformed into visible light — the aurora. Since there’s a LOT of energy, we’ll probably get the aurora borealis (the northern lights) down to the mid latitudes. This could mean parts of the central United States, the Midwest, the Mid-Atlantic and perhaps as far south as northern California. There’s even a chance that parts of the Mid-South could see the aurora IF a direct impact occurs and the orientation of Earth’s magnetic field cooperates. Scientists at the Space Weather Prediction Center in Boulder, Colorado are working to iron that out.
