After days of observing “large sunspot groups” and “several strong flares, NOAA’s Space Weather Prediction Center issued a G4 Severe Geomagnetic Storm Watch for Friday, May 10, through Sunday, May 12.
A graphic circulating with information about the watch said, in part:
At least five earth-directed coronal mass ejections were observed and expected to arrive as early as midday Friday, May 10, 2024, and persist through Sunday, May 12, 2024. This is an unusual event.

CMEs are explosions of plasma and magnetic fields from the sun’s corona. They cause…
