Brightening of Magnetic Loops Signal Flare Event (December 27, 2001)

  • Higher resolution version (TIF,3.3M)
  • On December 26, 2001, a solar flare blasted from Active Region 9727. It was observed in extreme ultraviolet as an area of strong brightening of magnetic loops in the lower corona that lasted for several hours. This marked the beginning of a high-energy proton event that pelted the SOHO spacecraft for almost a day. The active region is easily identified in the first image. Then the protons become visible in the second image as white snowy particles that strike the SOHO spacecraft. This continues through the last two images and beyond. The event was also associated with a coronal mass ejection.
