Sunspot Revisited

Sunspot AR2403 visible at sunset today through smoke and clouds 

Our Montana sunset is still smokey today, plus a little cloudy and a little lower down the ridge. Sunspot AR2403 is putting on a great show, doubling in size since yesterday and quadrupling in size since coming into view. Makes me wish I owned a false-C-hydrogen-alpha-Baader-Herschal-Grasshopper-wedge-thingamobob. Oh, and some fancy-pants software/disc space to process with. How long till Christmas?
