PICTURE OF THE DAYsee all »

Partial solar eclipse

This photographer was relieved by not having to deal with the Arizona monsoon during the partial solar eclipse October 23. The sky cleared nicely for him and he began the day shooting sunspots in the morning. Then in the afternoon, he shot the eclipse — complete with a terrific sunspot group. At maximum, the Moon covered 44 percent of the Sun’s disk from his location. (3.2-inch Zeiss apochromatic refractor, Imaging Source DMK51 CCD camera, 510 nanometer filter, taken October 23, 2014, from Payson, Arizona)
