ELLIPICAL HALOES AROUND THE SUN-Spaceweather has NO explanation for them!Not seen before!!

Very strange....
MYSTERIOUS SUN HALOES: Most sun haloes are circles. They surround the sun when sunbeams hit ice crystals in the air. The haloes this week in Finland, however, were not circular. Olli Leivo sends this picture from Lahti in Finland.......... [link to www.spaceweather.com] Finland has had a spate of elliptical halos over the last few days produced by ice crystals precipitating out of low clouds. The ones Leivo photographed are superb," says atmospheric optics expert Les Cowley. "Elliptical halos are rare and we do not understand how they are formed. A popular theory is that hexagonal plate-shaped crystals with very blunt pyramidal ends make them. But ray tracing simulations using these crystals do not reproduce the halo’s fine detail properly. Moreover, these crystals are physically unrealistic because crystal faces follow lines of atoms in the crystal lattice – blunt pyramidal ends do not! The mystery remains."
