From the raw images section I see an image with something strange to me. this one.
In case that URL changes, the full resolution image is here.
It is a picture of the atmosphere. There is a perfect circle (like an O, not a dot) in it. What is this? I assume it has to be some kind of instrument artifact since I have a hard time believing a storm could do this so perfectly and a shadow of moon should be a dot and not an circle.
