  • These images from LASCO C2 and C3 instruments on Dec. 2-3, 2001 give an excellent view of a coronal mass ejection (CME) as it maintains and enlarges its original shape as it expands outward. The C2 video clip shows that this image is the second of two CMEs in rapid succession which headed off to the right. CMEs are solar storms that blast billions of tons of particles out from the Sun at over a million kilometers per hour. The Sun, blocked by an occulting disk, is represented by the white circle. The bright object passing below the Sun is the planet Mercury.
