#circumhorizontal arc

[identifying-clouds]

Just saw this very cool looking rainbow phenomenon, also including some interesting clouds! 🤍

Woah! What we have here is some halo action going on!!!

We have cirrus fibratus, cirrus spissatus translucidus, cumulus humilis, and cumulus fractus clouds present here.

And in terms of halos, we have a 22° halo around the sun, and a circumhorizontal arc closer to the ground.

Great spotting!

Proud cloud

‘This photograph was taken on 7 June 2023 on a drive through Colorado, US. To cloud connoisseurs, this lovely optical phenomenon is recognised as a circumhorizontal arc. To those who encourage and support inclusivity, it might be interpreted as the sky celebrating Pride month.’

Circumhorizontal arcs We are all familiar with the haloes around sun or moon formed by light interacting with ice crystals or water droplets in the atmosphere. We usually have to be looking up at the sky in order to see them, but sometimes a similar phenomenon takes place on the horizontal plane. The light is encountering minute prisms of ice in the distant cirrus clouds creating a fiery rainbow effect parallel to the horizon. The sun must be over 53 degrees up in order for this to happen, and icy high altitude cirrus clouds need to be in the sky. The hexagonal prisms of ice also need to be aligned horizontally to refract the light in the necessary manner, so the phenomenon is quite rare. Loz Image credit: Todd Sladoje via APOD
