This movie
of the March 6, 2012 X5.4 flare was captured by the Solar Dynamics Observatory
(SDO) in the 171 Angstrom wavelength. One of the most dramatic features is the
way the entire surface of the sun seems to ripple with the force of the
eruption. This movement comes from something called EIT waves - because they
were first discovered with the Extreme ultraviolet Imaging Telescope (EIT) on
the Solar Heliospheric Observatory.
