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.
  • Several strong flares have been observed over the past few days and were associated with a large and magnetically complex sunspot cluster (NOAA region 3664), which is 16 times the diameter of Earth.
