Sunspot AR2470

[John W (John Wilkinson)]

I have been following sunspot AR2470 as it moves across the sun's disk. See my Ha images "Sun prom on Dec 17". This image was taken thru a Herschel wedge with 540 nm filter and Canon 550d camera to show the sunspot in different light. Thanks for viewing.

Nice catch John, I’m outside just now battling the clouds trying to grab a few images of this one.

Cheers
