Saturn, dark spot. Jan 14th 2015

Imaged Saturn this morning and have resolved a rather interesting dark spot in IR.

Obviously Saturn is rather low at the moment so the seeing was not great but it will rise quite rapidly over the coming weeks. I measure the spot to be at Lat +30.4 L3 17.2

Note that I have included an inset of the spot that has been more heavily sharpened.

I have also uploaded a polar projection of this IR data and the dark spot is also seen in the polar projection.

I had a look at the most recent 500 raw data sets from Cassini but the most recent runs have mainly been of Titan. There are a couple of Saturn images but none with this dark spot.

Regards
Trevor
