Space Weather News for Jan 19, 2010
FARSIDE SOLAR ACTIVITY: Over the past two days, NASA's STEREO-B spacecraft has detected two eruptions from an active region just behind the sun's eastern limb. The source of the blasts appears to be old sunspot 1039. The sun's rotation will begin turning the spot toward Earth this week, so there could be some Earth-directed solar activity in the offing.

ANNULAR SOLAR ECLIPSE: On Jan 15th, the Moon passed directly in front of the sun, producing a "ring of fire" solar eclipse over the Indian Ocean and surrounding lands. The eclipse gallery contains many must-see images.

May 2009 Sun's new coronal mass ejections
Space Weather News for May 6, 2009
NASA's STEREO-B spacecraft is monitoring an active region hidden behind the sun's eastern limb. On May 5, it produced an impressive coronal mass ejection (CME) and a burst of radio emissions signalling the passage of a shock wave through the sun's outer atmosphere.
Activity has continued apace today, May 6, with at least two more eruptions. The blast site is not yet visible from Earth, but the sun is turning the region toward us for a better view. Is a new-cycle sunspot in the offing? Readers with solar telescopes could see it emerge as early as May 7 or 8.
