The Moon just now in the UK. No idea what is creating the halo

That would be a 22° halo, a fairly uncommon atmospheric phenomenon where light refracts through hexagonal ice crystals in the atmosphere resulting in an average deviation from the angle it comes in at by around (funnily enough) 22°.

There are lots of other interesting atmospheric phenomena including sundogs, moonbows, and the much rarer 46° halo!

Oh nice, I've seen this before in Florida but was unable to capture it in my phone's camera. Didn't realise it had a name!

sundogs

You're just making things up now XD

[–] dirtySourdough@lemmy.world 7 points 1 year ago (1 children)

Though it sounds silly, sundogs are the name of an actual optic phenomena. They appear as bright spots on either side of the sun, aligned with where the halo may appear. Hence, they are "dogging" the sun.

Yarp, I looked it up. The etymology section is fun, I like to think there's no real meaning behind it, someone just called it that and the name stuck.

[–] jaybone@lemmy.world 3 points 1 year ago

No, that’s updog.

We saw the same tonight as well from northern Italy about 2 hours ago. The moonlight interacts with ice crystals in the air and creates this rainbow / halo 🤯

[–] ndguardian@lemmy.world 6 points 1 year ago

Yeah, if there’s an atoptics (I think that’s the word) community, they’d be all over that!

Jupiter just hangin on the right

[–] PlasticQuality7519@reddthat.com 3 points 1 year ago (1 children)

I could see it this week even in the middle of London

[–] casmael@lemm.ee 2 points 1 year ago

Yeah same can see it from Hornsey

I just took a picture of the moon, came out pretty good.

[–] Darthjaffacake@lemmy.world 1 points 1 year ago

Wow that really is good

[–] Thorry84@feddit.nl 3 points 1 year ago

Don't read any of the other explanations, they just spout off the same thing they want you to think!

I did my own research, it turns out this is due to ice crystals. The inside of the dome set on top of the flat earth is covered by LCD displays. These displays get cold in wintertime and ice crystals form within the displays. This causes all sorts of visual glitches, like these halos around the moon. When it warms back up the ice crystals go away and the moon looks normal again.

Don't let people fool you with bullshit stories about ice crystals in the so called atmosphere. It's a totally made up story, with just enough truth in it to make it believable.

"A ring around the sun or moon, means that rain will come real soon." Old sailors adage.

Have Spartans recently landed nearby perhaps?

Also that's Jupiter on the right, we got Uranus on Friday

No idea what is creating the halo

If not the cloud cover or other atmospheric conditions, the lens of the camera the image was taken with. Was the halo visible to the naked eye or only in the photo?

[–] YarHarSuperstar@lemmy.world 3 points 1 year ago (1 children)

I'm not op and I'm not near them but I saw the same halo with the naked eye last night with zero clouds.

[–] Kolanaki@yiffit.net 2 points 1 year ago

If you're far enough north, ice crystals in the atmosphere create a halo like that.

[–] unoriginalsin@lemmy.world -2 points 1 year ago

It's just moonlight shining through the buildup of the day's chemtrails.
