A grand Bottlinger's rings in diamond dust (2025-Jan-12, China.)

 A spectacular event of Bottlinger's Rings occurred on January 12, 2025, in Hemu(禾木), Xinjiang, China. For China, this was the first time the phenomenon was observed in diamond dust (rather than being captured from high-altitude aircraft). 'Javen嘉文儿', a user from the video website 'bilibili.com', directed his photography team to captured extensive footage. We are permitted to share the related files here.

Footages show a solar elevation angle of 11 to 12 degrees. The lack of ice crystal sampling is regrettable, and it is hoped that valuable ice crystal samples can be obtained the next time such event occurs.

Bottlinger's Rings from airplane

To help overcome our dearth of halos, here is another archive picture. It was taken in the morning over Iberian Peninsula in April 1997 by Frank Wächter using a 35mm lens. It shows elliptical haloes around the subsun called Bottlinger's rings.
