aurora alert: year’s largest solar flare

aurora alert: year's largest solar flare The largest so far this year, a category M6.6 solar flare is earthbound. A skywatcher alert has been issued for auroras in possibly lower as well as higher latitudes. Experts agree a cloud of radiation from a Coronal Mass Ejection (CME), will hit the Earth’s magnetic field on or about Feb. 15th. The source of the activity is sunspot 1158, which is expected to grow. Many thanks go to Oystein Lunde Ingvaldsen for his wonderful images like the one pictured. The captured Northern Lights image is from the present buffeting of the magnetosphere above Bo, a town in Norway. They are a wonder to behold!. You can enjoy more aurora pictures from another Norwegian, Bjorn Jorgensen, here.
