Mark,
You have captured a rare moonlight atmosperical phenomina, a moon dog,
as Danpbphoto states correctly.
This is from the UK's http://www.atoptics.co.uk/
"Sundogs are commonly made by the refraction of light from plate-shaped hexagonal ice crystals in high and cold cirrus clouds or, during very cold weather, these ice crystals are called diamond dust, and drift in the air at low levels. These crystals act as prisms, bending the light rays passing through them with a minimum deflection of 22°.
Even more rare are areas within the globe that have such intense moonlight, that a refraction can occur at night as well."
It appears you have captured one of these. IMHO I would leave it despite the suggestion of eliminating it.
Happy New Year!

Thanks for providing the link Angelo. One of many I found since many FM'ers PM'd me on where I heard of this.
The technical name of a moon dog is:
"paraselenae
Variant of paraselene
noun pl. paraselenae
a moonlike optical illusion caused by moonlight passing through ice crystals in the upper atmosphere"
Good catch Mark! Right place, right time makes for a rare photographic opportunity. Moondogs and sundogs can be there for 1 second, then gone!
Again great work!
Dan
