Just like predicting the daily weather, space forecasters use a variety of tools to gauge the impact of solar activity on Earth. This forecast indicates that the peak solar radiation from the coronal mass ejection will arrive in the morning eastern time in the U.S. today and then the plasma levels will drop off in the following hours. Today, NOAA's Space Weather Prediction Center said it expects this to be the largest coronal mass ejection since December 2006.
