SkyWatch Friday - Moon Halo

For better or worse I dragged myself into work today – time and deadlines wait for no man!
Another Kangaroo Island shot – maybe I should get some form of commission from their Tourist Board!
This is a Moon Halo.  It’s caused by light being refracted through six-sided crystals of ice floating in the upper atmosphere.  Because the ice crystals are the same size and shape you end up with a regular pattern being perceived – in this case a circle.
I think of it as the same way as I think about rainbows – a splendid thing to see and no less splendid for knowing how its formed.  Unweaving a rainbow – or in this case, unpacking a halo -  never reduces its beauty.
You can find more sky shots from around the world at SkyWatch Friday.
Enjoy the Skies.

We see these halos on rare occasions here in the northwest and it is an awesome sight! Haven't ever been able to get a good shot though! Yours are terrific, Stewart!

I once worked (as a secretary) for a geologist who said he wished he could go back to childhood and just admire rocks because they were beautiful, without analyzing their makeup. (Maybe he was in the wrong profession.) Your moon halo is beautiful, whether you are as ignorant as I am (or at ealst was before your explanation) or as smart as you are!
