Awasome Bottlinger Ring 2022. Elliptical halos and bottlinger's rings are simulated by the use of a monte carlo algorithm that includes multiple scattering. High multiple reflections are required to obtain a sufficient brightness of the elliptical halos.
Bottlinger's rings from airplane to help overcome our dearth of haloes, here is another archive picture. Even though this case is a marginal one, the elliptical halo appearing around subsuns is so infrequent that the photo is worth showing here ( 1). Bottlinger's rings have been seen twice also in.
