There are few better ways to start the day than being greeted by a startling sunrise. This rosy sunup was photographed on the morning of January 7, 2010 from Patagonia, Arizona. Perhaps the bubble-like features are remnants of mammatus clouds, or perhaps they’re oddly outlined altocumulus clouds? Whatever their name or nature, they were perfectly positioned to reflect the Sun’s rays on this winter’s morning. The longer path length of sunlight when the Sun is close to the horizon causes the shorter wavelength colors, blues and violets, to be scattered from our view. Though lacking a complete pallet to work with, the twilight sky can occasionally be lit up with the longer wavelength red and yellow colors.
