|The contrast would have been much better if I had set up on a tripod and took a longer exposure...|
The halo was so large that I could barely fit it in the lens. It looked much more like this excellent pic from the UK taken earlier in the evening in England...

This awesome effect is created when upper atmospheric ice crystals of a "just right temperature - and therefor just right angle" reflect the moon's light in the spherical upper atmosphere layer. Cirrostratus clouds were responsible for the beautiful effect.
I didn't know the UK had witnessed the halo when I took my picture, just wanted to capture a beautiful atmospheric effect... I find it so amazing that the layer of upper atmosphere ice crystals existed right across the Atlantic last night.
Hope you enjoyed the pics,
