Hi everybody

Tonight in clear skies I saw an enormous 'hole' around the moon.

The hole was kilometres wide and was perfectly spherical in shape, at
the 'edge' of this 'hole' there was a 'thick halo'. I have never seen
anything like this and attempted to get a picture as a record, but to
no avail.


It's probably a "moondog" or lunar halo, an effect of moonlight hitting
ice crystals in the upper atmosphe

They are fairly common here in North Dakota USA.
