http://www.cbsnews.com/news/sun-emits-huge-solar-flare-burst-of-plasma/According to this article, yesterday "the sun produced its biggest solar flare so far this year, a huge blast
that caused temporary radio blackouts throughout the Pacific."
In theory, what type and magnitude of a solar flare would be necessary to disable GPS? How common are such solar flares? In other words, what is the
real risk to GPS?
