Last night the Sun unleashed a large coronal mass ejection in our direction. Here is a compilation of images from SOHO's two LASCO cameras, plus a prediction from the new space weather prediction model that I learned about at the American Geophysical Union in December. The storm will arrive at Earth on March 8.

Solar flares from Skylab
