MARS-DIRECTED CME: A minor CME that left the sun during the late hours of April 28th is heading for Mars. En route, it will sweep past the Mars Science Lab spacecraft, which is carrying Curiosity to the Red Planet. According to a forecast track prepared by analysts at the GSFC, the cloud will reach the rover on May 4th. Fortunately, Curiosity is equipped to sense and study solar storms: video.
THWARTED ESCAPE: Solar activity is low, with only a smattering of minor C-class flares coming from a few 'active regions' scattered across the solar disk. An eruption from sunspot AR1465 on April 29th didn't even get off the ground. NASA's Solar Dynamics Observatory recorded the thwarted escape:

It was AR1465 vs. gravity, and gravity won.
Solar activity should remain low for the next 24 to 48 hours, with no more than a 1% chance of X-class solar flares. As the movie above shows, however, even a weak eruption on the sun is worth watching. Stay tuned for more. Solar flare alerts: text, voice.
