Details:
Here are two animations (with different rates) made from images acquired over 35 minutes, on July 26. They show the Evershed effect but also some interesting contact between the granulation of the light bridges and umbra of the spot. The granules in part of the light bridge are evolving much faster, while the ones in direct contact with the umbra are not moving much. AR 4492 is disintegrating slowly, which makes for a good subject for long term observation.
355 mm Newtonian with Red filter.
