EARTH-DIRECTED 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.
