Study the sequence of images depicting the magnetic field structure on the surface of the Sun as captured by the Helioseismic and Magnetic Imager
A sequence of images captured by the Helioseismic and Magnetic Imager (HMI), one component of NASA's Solar Dynamics Observatory. The images depict the magnetic field structure on the surface of the Sun, with white locations representing a positive magnetic field value, black locations representing negative magnetic field value, and grey areas representing zero magentic field value.
