Lunar Display in Switzerland


On Nov/11/2006 I observed a nice high moon halo display in Switzerland. Visible was a bright circumscribed halo and a infralateral or circumhorizon arc.

Beautiful! Is that 9° halo or artefact?

I am not sure. I didn't noticed a 9° halo visually. However it is on all photos ( http://www.meteoros.de/php/viewtopic.php?t=4711 ). I used a Nikon D70 and Peleng 8mm lens. It was at 3:42 UTC in the moring and I found nothing to block the moon. Full moon was 6 days before.

Supralateral? Supralateral forms when sun is at 32 degrees or below the colored arc under the 22/circumscribed halos is either circumhorizon arc or infralateral arc.

Seems like 9 halo, but can't be sure. Martin has the same thing.

The Bates Motel on the left looks great.

Am I the only one wondering why the bottom of the halo is so much better defined than the top? Mark, was that typical throughout the display? And how long did the display last? Thanks.

Dear Walt,
I took the photos from 3:36 to 3:48 UTC. The bottom is better defined on all images during this 12 minute time periode. Then the whole display started fading out from the top of the halo. The clouds moved from NNW to SSE.
