SPECTACULAR BLAST: A massive cloud of plasma exploded over the eastern limb of the sun this morning (Feb. 24th around 0730 UT), heralding the approach of a new active region. The spectacular blast, which produced strong radio emissions, a coronal mass ejection, and an M3-class solar flare, was not Earth-directed. Future eruptions could be, however, as the sun's rotation turns the blast site toward our planet in the days ahead. Check http://spaceweather.com for images and movies.
