A coronal mass ejection #CME produced during yesterday’s X1.1 #solarflareevent is coming directly our way at Earth. Experts are expecting the bulk of the #ejecta to arrive on August 18. But, they say, we could also see an early arrival on August 17. The impact of this solar material with Earth’s magnetic field should boost #auroraldisplays.
