CME will likely pass above Earth's north side on Jan 22, auroras expected

NOAA/SWPC have determined that the CME from Active Region 1402 near disk center from the latest M3 solar flare will likely pass above (north) of Earth. This glancing blow will cause just G1 (Minor) Geomagnetic Storm activity. We can expect first signs  starting from

M3.2 solar blast from Sunspot 1402 produced Earth-directed CME

The long-duration blast at active region 1402 produced M3.2 solar flare and CME which is heading toward Earth. This was two-wave flare and first CME wave was overtaken by the 2nd wave due to its higher speed velocity.The major bulk of the plasma cloud appears to be

Solar activity increasing - M-class flares, auroras and magnetic filaments

Recently formed sunspot 1401 awoke yesterday afternoon and produced an M1.7 solar flare at 19:12 UTC. AR 1401 has a Beta-Gamma magnetic configuration which could lead to further solar flares. NOAA forecasters estimate a 15% to 20% chance of polar geomagnetic storms
