This image of the entire Sun was taken at a wavelength of 617.3 nanometers. Light at this wavelength originates from the visible solar surface, the photosphere. A cooler, darker sunspot is clearly visible in the disk, and -- as a visual comparison -- a depiction from ALMA at a wavelength of 1.25 millimeters is shown.
