The 9° halo was visible for only a few minutes, so I had no time to take enough photos for stacking and finding out whether there were other odd radii. After it disappeared, there was a circumscribed halo in the sky for a long time.

9° halo
Csak pár percig látszott a 9°-os halo, és nem volt időm elég képet csinálni az átlagoláshoz. Így sajnos azt sem tudom, volt-e más halo is piramis-alakú kristályokból. Miután eltűnt, sokáig körülírt halo látszott az égen.
