A layer of stratocumulus clouds over the Pacific Ocean, in this image from Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired on June 20, 2012, served as the backdrop for this rainbow-like optical phenomenon known as a glory. Glories generally appear as concentric rings of color in front of mist or fog.
The photo above shows radiation fog overspreading Alhandra, Portugal on the River Tagus, about 12 mi (20 km) north of Lisbon. Only the steeple and top of Alhandra’s central church (Igreja de Alhandra) can be easily detected. Photographer António Ferreira Pinto; Antonio’s Facebook Web site
