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 X5.7-class flare, which caused an S3 radiation storm on Earth fifteen minutes later as energetic protons bombarded the ionosphere. It was the biggest solar radiation event since 1989. The proton event was four times more intense than any previously recorded since the launches of SOHO in 1995 and ACE in 1997. The flare was followed by a full-halo coronal mass ejection and a geomagnetic super storm on July 15-16. The extreme level, G5, was peaked in late hours of July 15
The Bastille Day event was observed by Voyager I and Voyager II, thus it is the farthest out observed solar storm.
Famous quotes containing the words day and/or event:
“When parents fail to set appropriate limits, children may feel more vulnerable at night: the aggressive urges that have not been “tamed” by day may be terrifying to a small child alone in the dark.”
—Cathy Rindner Tempelsman (20th century)
“We can glut ourselves with how-to-raise children information . . . strive to become more mature and aware but none of this will spare us from the . . . inevitability that some of the time we are going to fail our children. Because there is a big gap between knowing and doing. Because mature, aware people are imperfect too. Or because some current event in our life may so absorb or depress us that when our children need us we cannot come through.”
—Judith Viorst (20th century)
