Comments: Something rather strange has popped in Saturn’s Southern Hemisphere that I have not previously seen. Imaged Saturn August 7th in good to very good seeing, my 685nm IR data reveals a dark very elongated structure in the Southern Hemisphere extending below the ring shadow. It extends in Latitude from approx Lat-24 to –30 and extends in Longitude from approx L3 305 to L3 277 it also tapers slightly to the East. I have it centred on the CM initially and have tracked it all the way to the P limb. I have not previously seen a structure like this at Saturn. Initially I thought it was only resolved in IR but on closer inspection there is a hint of its structure in the R and RGB data but at those wavelengths it is not dark. All of this is best seen in the animations. To help with the analysis of this structure I have positioned the insets for each data set in the same relative position. It is quite interesting to progress through all data sets commencing with the initial IR data set. Other detail I have measured in these data. From the IR data, a bright spot at approx Lat+57.6 L3 330.5, a minor EZ / NEB ripple at Lat+15 L1 241.4, there are multiple low contrast bright and dark features in the EZ I have marked a dark spot at Lat+6.7 L1 208.4 R channel data also resolves a chain of bright spots along the Southern edge of the NTrB I have marked one at approx Lat+30.6 L3 316.2. A dark EZ spot at approx Lat+7.7 L1 258.5 along with a bright spot at approx Lat+0.8 L1 228.1 RGB data also resolves a faint bright spot at approx Lat+46.4 L3 327.7, again the RGB polar projection resolves the polar hexagon relatively well.
