On April 9, 2017, a dark solar filament exploded hurling a powerful CME into space. At first it appeared that the CME would miss Earth, but a new analysis by NOAA forecasters suggests that a glancing glow is possible on April 15th. G1-class geomagnetic storms are possible when the CME arrives this weekend. The above video of the eruption was recorded by NASA’s Solar Dynamics Observatory.
