What causes halos?

We get numerous messages throughout annually from world who’ve just spotted a big ring or one of light about the sunlight or moon. Scientists speak to them 22-degree halos. They bear this name since the radius that the circle around the sun or moon is roughly 22 degrees.

You are watching: Clouds behind the sun

There’s one old weather saying: ring roughly the moon means rain soon. There’s truth to this saying, due to the fact that high cirrus clouds frequently come prior to a storm. Notice in these photos the the skies looks fairly clear. After all, you can see the sun or moon. And also yet halos room a sign of high, slim cirrus clouds drifting 20,000 feet (6 km) or an ext above our heads.

These clouds contain numerous tiny ice cream crystals. The halos you see are resulted in by both refraction, or dividing of light, and additionally by reflection, or glints of irradiate from these ice cream crystals. The crystals need to be oriented and also positioned simply so v respect to her eye, in order because that the halo to appear.

That’s why, prefer rainbows, halos about the sun – or moon – are personal. Anyone sees their own details halo, made by their own details ice crystals, i beg your pardon are various from the ice cream crystals make the halo of the person standing next to you.

Take care when photographing solar halos. Pointing a camera directly at the unobscured sun can damage it. Never ever look directly at the sun, also when the is visible through clouds.

Eliot Herman created on may 5, 2018: “This mirrors the readjust that emerged over 7 minutes together a lunar aur emerged. It then persisted for around 40 minutes and disappeared with raising clouds. Return it shows up the halo is forming from one odd shape, what is in reality illuminated is the edge of the clouds just before the halo formed as the clouds drifted in former of the moon. Yet it does have a pretty illusion of an odd-shaped halo then coming to be round.”Robert green of London caught this glorious solar gloriole on respectable 12, 2017, from Suðuroy, Faroe Islands. His daughter Mia is standing beneath!

Are halos much more common in ~ high latitudes?

We request Les Cowley the the website Atmospheric Optics if halos around the sun and also moon are an ext frequently viewed at high latitudes and also less frequently seen closer come the equator. That said:

That’s a great question the is not basic to prize accurately since no aur frequency statistics are gathered except in one or 2 mid-latitude europe countries.

We need to distinguish in between (a) halos developed by low level diamond dust during really cold weather and also (b) halos developed by ice crystals in high cirrus cloud.

Obviously (a) halos only occur in polar areas or countries with really cold winters (Canada for example is not high latitude).

(b) Halos deserve to occur everywhere on the planet throughout winter or summer. Their frequency depends on the frequency the cirrus coverage and also whether the has had a background such that it contains halo developing crystals. The last is difficult to predict. Because that example, there are significant differences in gloriole frequencies and types of halos across even 200 miles <300 km> in the U.K.

Sheryl R. Garrison in Idaho recorded the November 14, 2016, supermoon. She wrote: “I’ve recorded lunar halos before but tonight was a very first for me to capture one v an arc … The arc didn’t last because that long, just enough time for me to grab the tripod.” by the way, this is a special type of 22-degree lunar halo, called a circumscribed halo.

If you check out a halo, an alert this!

Because moonlight isn’t an extremely bright, lunar halos are mainly colorless, but you could notice an ext red top top the inside and more blue on the external of the halo. These colors are more noticeable in halos about the sun. If you perform see a halo roughly the moon or sun, an alert that the inner edge is sharp, while the outer edge is more diffuse. Also, notice that the sky neighboring the halo is darker 보다 the rest of the sky.

Bottom line: Halos around the sunlight or moon are brought about by high, thin cirrus clouds drifting high over your head. Tiny ice crystals in Earth’s atmosphere create the halos. They perform it through refracting and reflecting the light. Lunar halos are indicators that storms space nearby.
