On the evening of 24.03, Dione, the second densest moon of Saturn, revolved close to Saturn's southern pole. So far there is only one submission of Saturn photo around that date - they are from John Earl, the well known Australian astrophotographer.

John took the first photoon 23.03. If you zoom the image to 200% you will spot a blurry dot a little left from the pole. Could that be Dione?
