WEEKEND SOLAR FLARES:

This weekend, magnetic fields around sunspot 1069 became unstable and erupted--over and over again. On May 8th alone, the active region produced more than half a dozen flares. High-resolution movies from NASA's Solar Dynamics Observatory show that even the "minor" eruptions were jaw-dropping spectacles.
