STRONG FLARE: For the second time in three days, an active region just
over the sun's east limb has exploded, producing a strong solar flare
and CME. The blast on May 3rd registered M5--not quite an X-flare, but
still strong considering that the edge of the sun partially eclipsed the
explosion as seen from Earth. Solar rotation is turning the active
region toward Earth, and it should emerge later this weekend. Visit http://spaceweather.com for updates.
