Nearly a dozen coronal mass ejections in less than four days (May 3-6, 2012) may serve as a reminder that the Sun is approaching its period of maximum activity, expected to peak next year. STEREO (Ahead) from its position over 100 degrees ahead of Earth, captured several major eruptions, with most of them heading way to the right (i.e., away from Earth). In these coronagraph images the Sun is represented by the white circle. The black occulting disk blocks out the Sun and some of the corona so that we can see the faint structures beyond that.
