"Info: "Radio-Active" Solar Flare"
Space Weather News for Feb. 14, 2011
SOLAR ACTIVITY: Solar activity increased sharply over the weekend with
the eruption of an M6.6-class solar flare from behemoth sunspot
1158. The blast produced a strong burst of radio waves heard in
the loudspeakers of shortwave receivers around the dayside of our
planet, and it appears to have hurled a faint coronal mass ejection
toward Earth. Sights and sounds from the event are highlighted on
today's edition of http://spaceweather.com.
