Description:
The sun remains very active with 65 visible sunspots today. This image was taken at about noon from our backyard in Alpine. Heliophysicist C. Alex Young of NASA Goddard Space Flight Center reported this today on EarthSky.org: Sunspot region AR3848 released an X1.8 flare at 1:56 UTC on October 9, and the flare produced an associated coronal mass ejection (CME) which is now headed straight for Earth. NOAA has issued a G4 (severe) geomagnetic storms watch. It could mean auroras visible in the lower-tier U.S. states, including Northern California. The flare accelerated solar particles to near the speed of light, creating a solar energetic particle storm, which also came our way yesterday and was detected by our spacecraft.
