Sun Twister Eruption

Source - Space Weather News for Oct. 28, 2010:

SUN TWISTER: Earlier today, NASA's Solar Dynamics Observatory (SDO) recorded a spectacular eruption on the sun's northeastern limb. An unstable magnetic filament hundreds of thousands of kilometers long pirouetted and launched a fragment of itself into space. Earth was not in the line of fire, but the SDO movie is worth seeing anyway. Visit for cinema.

ASTEROID FLYBY: Asteroid 2003 UV11 will fly past Earth on Oct. 29th and 30th at a distance of only 1.2 million miles. Experienced amateur astronomers should have little trouble photographing the 600-meter wide space rock as it glides through the constellation Pegasus on Friday night, glowing about as brightly as a 12th magnitude star. Observers in North America and Europe are favored. Check for ephemerides and more information.
