Naked-Eye (with Proper Filtration) Sunspot
Posted by DaveMitsky on Monday, November 18, 2013 4:28 PM

Using black polymer solar shades, I'm fairly certain that I was able to see the large sunspot AR 11899 that is currently close to the Sun's center without magnification this afternoon.

I definitely saw AR 11899 as a "naked-eye" sunspot earlier this afternoon using black polymer and Mylar solar shades.

AR 11889 was visible once again without optical aid on Wednesday afternoon.  

After I put my solar shades away, I managed to set up my 40mm f/10 Coranado PST with one hand and observed the large sunspot and two smaller ones (AR 11896 and AR 11903), along with a phage region, several filaments, and one fairly large prominence on the Sun's trailing limb using an 8-24mm Vixen zoom eyepiece set at 24, 16, 12, and 8mm.
