EARTH-DIRECTED ERUPTION: On Saturday, Oct. 17th, starting around 18:24 UT, a spotless active region in the sun's southern hemisphere erupted, hurling a faint coronal mass ejection (CME) in the general direction of Earth. SOHO's extreme UV telescope recorded this movie of the blast. High-latitude sky watchers should be alert for auroras on Oct. 19th or 20th when the CME arrives.
