Narrow-band image of the Sun as seen with VTF

Caption

A narrow-band image of the Sun at a wavelength of λ=588.9nm, that of a well known solar sodium line also known as the “NaD line.” The image was acquired during recent first light efforts with the VTF at the Inouye, and shows how precisely the structures within a sunspot are resolved. Each pixel in the original version of the image corresponds to 10 km (or 6.2 miles) on the Sun.
