Yesterday's solar flare was not aimed directly at Earth, but it did cause a minor geomagnetic storm yesterday. The storm has since subsided, but another wave of geomagnetic activity could follow, according to forecasters at the Space Weather Prediction Center, a division of the National Oceanic and Atmospheric Administration (NOAA).

"The G1 (Minor) Geomagnetic Storm of the early hours on October 9 has weakened, and now forecasters await another shock in the next few hours," officials at the Space Weather Prediction Center wrote in an update yesterday.

Tuesday's M-class flare erupted from a sunspot region called AR1865, which will be turning to face Earth over the next few days, according to Spaceweather.com

A different region on the sun also appears to be waking up, according to the Space Weather Prediction Center. "That active region will be Earth-facing for the next 11 days or so, possibly fueling additional eruptions from an otherwise quiet sun," experts said in an update.
