Austin Solar Corona
April 08, 2007
The remarkable solar corona shown above was visible all afternoon on January 5, 2007 from Austin Texas. Coronas typically result from sunlight being deflected by cloud droplets, but no obvious clouds were visible this day -- just clear, blue sky. Pollen grains of uniform size may also produce coronas, which is likely the case here. This photograph isn't enhanced in any way during post-production. I only had a small camera with me at the time, so I used my sunglasses as a filter.
