Sunspot complex AR2192 is the largest I have seen in a long time. Easily visible without a telescope, simply using appropriate eye protection. It is quite large, more than ten times the diameter of the Earth. There are reports of it being noticed at sunset.
I photographed the sunspot during lunch fron Waimea, setting up a little telescope next to my vehicle in the Keck parking lot. The photo was taken using a TV-76mm telescope, the EOS-M camera and a Baader solar film filter, the same setup I viewed the Venus transit with.
Of course there was a partial solar eclipse today, visible across western North America. Photos of this enormous sunspot and the eclipse are now being posted across the web. Unfortunately this eclipse was not visible from Hawai’i. If you have not taken a look, I urge you to step outside with your solar viewing glasses and take a quick look. You do have solar viewing glasses handy… Right?
