Space Weather News for April 27, 2008

STRANGE SOLAR FLARE: No sunspots? No problem. Yesterday the blank sun unleashed a solar flare without the usual aid of a sunspot. At 1408 UT on April 26th, Earth-orbiting satellites detected a surge of X-rays registering B3.8 on the "Richter scale" of solar flares. That's a relatively minor flare; nevertheless, the blast sent a "solar tsunami" shock wave rippling through the sun's atmosphere and also launched a coronal mass ejection. The CME is expected to reach Earth late on April 28th or April 29th, possibly sparking high latitude auroras when it arrives. Visit http://spaceweather.com to view images, movies and updates.
