Sun - 30th October

Sunny days are likely to be few and far between as we head towards Winter, so I thought I'd capture another solar white light image while I could.
The large sunspot group AR1117 is nearing the limb and will soon leave the visible disk. Another spot is creeping around the edge of the disk opposite AR1117. It will be interesting to see how this develops. The umbral region is just visible in the area of faculae, which themselves are enhanced by their contrast against the slightly darker limb region.


AR1117 nears the edge of the disk.
