Summer halo?

Halos, arcs, sundogs, and the like are formed by the refraction of sunlight by ice crystals in the air. Ice is more likely to form in the winter, but even in the summer you can get it up high in the atmosphere.
 
Is August still summer? We have ground frost warnings for tonight. I blame global warming.

Saw a beautiful ring around the moon last winter, at Baku airport, with secondary "dogs" at the 90 and 270 positions. Full moon too.
And my camera was in my checked luggage.
 
We have a very unusual and late summer here in Finland. I missed a wonderful chance to take a picture of a truly magnificent halo last winter. It had extra suns top, below, left and right of the Sun and a halo connecting these additional "suns". I just stood there and looked at it for several minutes.
 
Bah.

All these "sleptics" are part of the conspiracy.

These summer halos are obviously a result of the chemicals being sprayed on an unsuspecting populous by passing jets. Ever notice those exhaust trails?

:D

On the serious side, isn't this just a rainbow that's higher up? Couldn't it be caused by water clouds as well as ice? Just curious, I don't really know much in-depth about atmospheric phenomena.

It did have colours. All haloes supposed to be clear white?
Come on people, we need some experts here!
 
Rainbows happen opposite the Sun in the sky because the raindrops bend the light twice, sending the light back toward you.

A halo is form light that bends once, toward you. There can be some separation of colors, but it's usually subtle. The sundogs can be strikingly colored.

Huntsman / Vagrant- In the UK, a "rainbow higher up" (I like that) is called a "glory". If you are high enough- as in an aircraft above cloud- these are circular rainbows. Quite a common sight from planes in fact. You get them on mountains too- the Brocken Spectre of the Hartz Mountains fame is often surrounded by a glory. Got some pics somewhere. Take a week to find though. Google it.
