Strong Geomagnetic Storm Predicted

A CME hurled into space by yesterday's X4.5-class solar flare will graze Earth on Sept. 16th, according to a NASA model. NOAA forecasters are predicting a strong G3-class geomagnetic storm when the CME arrives. During G3 storms, auroras can sometimes be seen with the naked eye from mid-latitudes--e.g., as far south as California, Missouri and Colorado in the USA. On Sept. 16th, however, bright moonlight could mitigate the display.
