Sunspot 1081 unleashes flareSpaceweather.com reports that on June 12 at 0055 UT, the new sunspot 1081 unleashed an impulsive M1-class solar flare and Type II radio burst. NASA's Solar Dynamics Observatory recorded the blast in high-resolution The explosion hurled a billion-ton coronal mass ejection (CME) off the sun's western limb; the cloud will probably not hit Earth. The explosion also produced a Type II radio burst. "Although the Sun was setting here in New Mexico, I was able to record the burst at 28 MHz and 24 MHz," says amateur radio astronomer Thomas Ashcraft. The M2-flare was followed at 0917 UT by an even more picturesque C6-flare. SDO recorded that one, too. More flares seem likely as restless sunspot 1081 continues to grow. Readers with solar telescopes are encouraged to monitor developments. An audio clip, video and still frames can be see on the SpaceWeather website at
