Three Years of Solar Dynamics Observatory Images

Solar Dynamics Observatory image of the sun based on a wavelength of 171 angstroms, which is in the extreme ultraviolet rangeIn the three years since it first provided images of the sun, NASA’s Solar Dynamics Observatory has had virtually unbroken coverage of the sun’s rise toward solar maximum, the peak of solar activity in its regular 11-year cycle.
