Sun activity February 20, 2023: The storm is coming!
Today’s top news: Current solar activity is low, as we wait for the expected G1 (minor) geomagnetic storm. The impact of the Earth-directed component of the coronal mass ejection (CME) from the X2.2 flare has not happened yet as of this writing (11 UTC on February 20), but it is imminent. The possible extent of the resulting geomagnetic storm has been downgraded to a range of G1 (minor) to G2 (moderate). This will still mean a lot of auroral activity from North America to northern Europe. Now time and space will tell! Still waiting … waiting … Clear skies to all the aurora watchers!

Last 24 hours: Sun activity is low, with 19 C flares. The largest event was a C7.1 flare from sunspot region AR3226 at 7:13 UTC on February 20. Today the sun has seven numbered sunspot regions.
Next 24 hours: The forecast is for a 99% chance for C flares, a 50% chance for M flares, and a 15% chance for X flares.
