Caption: Figure 5.

An animation of the super-resolution reconstructed results from 2017 September 1–9, comparing the input HMI images (left) to the SR images (right). The animation runs for 56 s, showing the much better typical dynamics of a sunspot from the reconstructed images. These improved dynamics include materials moving away from sunspots in the outer part of the penumbra and inward in the inner part.
