I saw this big ring around the moon last night (Feb 13 8pm), what phenomena is this?

Looked really cool. It lasted about 25 minutes or so before fading away.
I had to take 4 sec exposure to capture it, so the moon is blown out.
This is @ 15mm on my T1i, took up the whole frame (un-cropped)

I believe that it's ice crystals in the upper atmosphere refracting the moonlight. Still a neat picture!

yeah it is ice in the upper atmosphere

Folklore has it that a ring around the moon signifies bad weather is coming... The ice crystals that cover the halo signify high altitude, thin cirrus clouds that normally precede a warm front by one or two days. Typically, a warm front will be associated with a low pressure system which is commonly referred to as a storm....
It is believed that the number of stars within a moon halo indicate the number days before bad weather will arrive."

What's the green thing at about 4 o'clock in reference to the moon?

It's called a moon halo and you did a good job capturing an image of it . The green thing just below and right is internal reflection of the lens causing the moon reflection to look green .

Aaah, a bit like when you take a photo of the sun, you get something like lens flares (or whatever they are called)?

Yes that would be Lens Flare.

Awesome picture BTW!

Thx guys, I took the kids outside to show them as well, took this shot, then read them bedtime stories.....

I took 3 exposures via manual, 1 sec, 3 sec, and 4 sec, then a "proper" exposure of 1/200 sec.
Boy, the moon sure is overexposed but the only way to capture the visual my eyes saw.
I was gonna PP the proper exposed moon into the shoot...but that's too much work!

Nice! Don't see too many 22° halos around the moon. I actually see more coronas around the moon then the halos

What's the difference between a halo and corona?

Halo caused by refraction
Corona caused by diffraction

Here is a corona around the moon
