Moderate G2 geomagnetic storm due to CME effects

Minor G1 geomagnetic storm levels have been observed according to the Wing-Kp index during the past 24 hours with the NOAA SWPC even reporting one period where the moderate G2 geomagnetic storming threshold was reached. Cause of this activity is a series of weak coronal mass ejection passages from likely a filament eruption and two lesser C-class solar flares. It was unsure if these coronal mass ejections would arrive at Earth but the solar wind data from ACE show two, possibly even three separate shock passages which managed to spark stunning aurora displays at high latitude locations during the past 24 hours. Keep on reading for some stunning auroral images taken the past night by photographers around the world.
