News about geomagnetic storm, northern lights

What's brewin' in the solar wind—an update: Current storm conditions are: Radio R1, Radiation S1, Geomagnetic G4. Solar wind speeds are still high (~800 km/s), but the Bz field is close to zero, so G4 conditions are unlikely to hold. Will a following CME turn the lights back up? pic.twitter.com/1JaXDPFN2K

Woah, G5 (extreme) geomagnetic storm conditions have been attained due to the recent CME(s) from AR 13664, with solar wind speeds at ~750 km/s and the north–south (Bz) magnetic field component almost reaching –50 nT. Enjoy the aurora show out there! 💫 pic.twitter.com/GAriVKKqnY

Why do we get auroras on Earth after eruptions occur on the Sun? A thread. 🧵 ⬇️⬇️⬇️ (Images: Left: a solar flare captured by NASA's Solar Dynamics Observatory. Right: Aurora seen from Lummi Island, Washington, at 10:54 p.m. PT on May 10, 2024. Credit: Jeff Carter) pic.twitter.com/0seln79n0p

If you spot aurora from this major solar storm, you can #DoNASAScience by making a report to participatory science project www.aurorasaurus.org! pic.twitter.com/QF25i6u0SI
