L’OPOD di oggi va a Adeel Shafid per questa ripresa della corona lunare:



Ecco le parole dell’autore che spiega il fenomeno: “A corona (plural coronae) is an optical phenomenon produced by the diffraction of sunlight or moonlight by individual small water droplets or tiny ice crystals of a cloud. In its full form, a corona consists of several concentric, pastel-colored rings around the celestial object and a central bright area called an aureole. The aureole is often (especially in case of the Moon) the only visible part of the corona and has the appearance of a bluish-white disk which fades to reddish-brown towards the edge. The angular diameter of a corona depends on the sizes of the water droplets involved; smaller droplets produce larger coronae. Coronae differ from halos in that the latter are formed by refraction (rather than diffraction) from comparatively large rather than small ice crystals. I was able to capture this phenomenon tonight from the skies of Lahore as thin and hazy clouds were passing overhead creating a circle full of colors around the moon.”
