🛰 SPACE WEATHER - We're keeping an eye on some devolving space weather. Here is what is happening.
- Over the last couple of days, the Sun launched three separate Coronal Mass Ejections (CMEs)—massive blasts of solar plasma and magnetic fields. Because the third blast was moving much faster than the first two, it is essentially "swallowing" them on its way to Earth. This creates one heavily compressed, highly energized shockwave.
- When this solar energy collides with Earth's magnetic field, it channels particles down into our upper atmosphere, exciting gas molecules and creating the glow we know as the aurora.
- If the auroras reach far enough south to be visible in NC, depends on intensity.
More info as we learn more today.
The current forecast calls for combined CME arrival around mid-afternoon EDT of June 4, with up to G3 levels possible afterwards. CME passage would likely continue into the evening and possibly overnight hours of June 5. Stay aware at spaceweather.gov
