I took this photograph from a location near Chambers Hill, Pennsylvania, with a Mylar-filtered 114mm f/7.9 Celestron C4.5 Newtonian and a Pentax K1000 SLR camera using eyepiece projection via a 26mm Tele Vue Plössl. The film employed was Fujifilm Superia X-TRA 800. The two huge active regions 10486 and 10488 both attained a width of approximately 175,000 kilometers, nearly 14 times Earth's diameter and were easily visible to the properly filtered unaided eye. Region 10486 was very active, releasing a number of extremely powerful solar flares.
