Sunspot 2320 growing slowly

A static tripod mounted Panasonic Lumix DMC-FZ72 bridge camera at 60x optical zoom, fitted with a Baader solar filter, was used to image the Sun. The camera was set to burst mode, ISO-100 and 1/800s exposure at f/5.9. Images were captured in bursts of three. 60 images, precisely cropped and registered in Nicola Mackin's AstroCrop software were stacked and wavelet processed in Registax 5.
