Lunar & Venusian Coronae imaged at Veszprém, Hungary by Tamás Ladányi (site, TWAN).

At top is a lunar corona taken just after the end of the penumbral lunar eclipse of 9th of February. At right is the cathedral of the old city of Veszprém.    The lower picture taken about an hour later shows a Venus corona. The scale is 1.8X that of the upper picture. Cirrus cloud was present and ice crystals or supercooled water droplets might have formed it. If the former, the corona's size indicates that the crystals would have been too small to be oriented by aerodynamic drag forces. Oriented crystals could produce a non circular corona.
