| Belarus Lunar Elliptical Halo Imaged by Anton Dodonov March 25, '13 at Rechitsa, Gomel Region, Belarus. Canon 550D EF 50mm 0.5s at f/3 ISO 800. The long axis was vertical in the sky. Another unusually large elliptical halo. The oval has a partial second, outer, companion indicating that two discrete ray paths were possible through whatever crystals made it.
