Sept. 5 - NASA's orbiting Solar Dynamics Observatory (SDO) has recorded more spectacular activity in the Sun's atmosphere, with a solar flare whipping half a million miles into space, and sending a cloud of electrically charged particles in Earth's direction. Rob Muir reports.
==RESENDING WITH NEW VIDEO== The flare had been observed hovering inside the Sun's atmosphere before it exploded on August 31st, sending a filament more than half a million miles into space at a speed of 900 miles per second. NASA says the charged particles ejected by the flare did not travel directly towards Earth, but did deliver Earth's magnetosphere a glancing blow, producing aurora but no damage. Images of the flare were captured by NASA's Solar Dynamics Observatory, the most advanced spacecraft ever designed to study the Sun. With four telescopes recording in differemnt wavelengths, it transmits highly detailed images of the sun every ten seconds, seven days a week. This latest ejection is part of an 11-year cycle of activity which is expected to peak next year.
