Bastille Day event

<!-- Unsourced image removed: -->The Bastille Day Flare or Bastille Day Event was a powerful solar flare on July 14, 2000 occurring near the peak of the solar maximum in solar cycle 23. Active region 9077 produced an X5-class flare, which caused an S3 radiation storm on Earth fifteen minutes later as energetic protons bombarded the ionosphere. The flare was followed by a full-halo coronal mass ejection and a geomagnetic super storm on July 15-17.

The Bastille Day event was observed by Voyager I and Voyager II, thus it is the farthest out observed solar storm.
