M8.7 Solar Flare + Proton Event - SDO, SXI, Lasco (Jan 23, 2012)

The strong M8.7 solar flare also generated a strong S3 Level Radiation Storm. This is the strongest Proton Event since 2005. This video shows the Flare captured by SDO and the Goes 15 Solar X-Ray imager, followed by a Lasco C3 movie. You can see the protons racing past the Lasco camera out ahead of the Coronal Mass Ejection (CME).
