© Jeremy Vohwinkle, 25 June '26. "Atmospheric Optics, halos, sundogs, arcs" near Mount Baker (aka Kulshan/Koma Kulshan), North Cascades, Washington, USA. Some of the phenomena: Circumscribed Halo - oval shaped solar halo around the 22° Halo, and part of a Parhelic Circle - the big arc bisecting the halos.

Interactive diagram of how a Circumscribed Halo changes depending on the solar altitude:

Sun Halo With Parhelic Circle by Levin Dieterle

Halos around the sun or moon happen when high, thin cirrus clouds are drifting high above your head. Tiny ice crystals in Earth’s atmosphere cause the halos. They do this by refracting and reflecting the light. Lunar halos are signs that storms are nearby. [Earthsky]

A parhelic circle is a halo, an optical phenomenon appearing as a horizontal white line on the same altitude as the sun, or occasionally the Moon. If complete, it stretches all around the sky, but more commonly it only appears in sections. [**]
