These three images show a coronal mass ejection, or CME, erupting into
space on May 26, 2013. The pictures were captured by the ESA/NASA Solar
Heliospheric Observatory with its coronagraph, which blocks out the
bright light of the sun to better see its dimmer atmosphere, the corona.

On May 26, 2013 at 3:24 p.m. EDT, the sun erupted with a coronal mass
ejection or CME, a solar phenomenon that can send billions of tons of
solar particles into space that can affect electronic systems in
satellites. Experimental NASA research models show that the CME was not
Earth-directed and it left the sun at 550 miles per second. It may,
however, pass by STEREO A and its mission operators have been notified.
The spacecraft can be put into safe mode if warranted.
