If it was an hour after sunset and you were facing south I'd tend to think it was an Aurora. It has been known to have been seen before from about your latitude Astrogen.
I've just been scanning a 22 deg lunar halo I shot in April. To my surprise I just noticed what appears to be 'an exceedingly rare' 9 deg halo inside the 22 deg halo. I'm just checking on the net now for how rare it is. I'll be seeking other opinions about it at meteoros.de forum and from Les Cowley too I hope. I'll post it here shortly.

Great images Mick ErnM I was just having a look at your image in Photoshop “hope you don’t mind” For something different have a look at each channel & see how the colour is depicted in the image. You can see a lot more,going through the Red, green, blue channels then looking at the mixed image. Quite interesting. :cheers: Ray

Ray, Thanks for pointing that out. Yes, the 9 deg. ring shows up most clearly in the Green channel. Interesting how clear the ring shows up then.
The strangest thing to me about these halos is how the 22 deg halo appears to be squashed downwards while the inner 9 deg halo is squashed the other way (inwards on the sides). Weird. Unusual halos (and rainbows) can some times occur like this but seeing them squashed or distorted in the opposite directions seems very weird. I'll be interested to see what Les Cowley can work out from this shot.
I think I must have shot this on the 5th April full moon. Volkl, you have a shot of a solar halo on page 12 of this thread. Do you have a specific date for when you took that ??? I believe it might have been around the same day given the similar conditions at the time. In fact I remember seeing yours and thinking - ah yes, I got a lunar one around that time, but it was still in the camera at the time. Ern

Very interesting all right I am interested in seeing if some one has an explanation for this one. I will be happy to find out the answer. Try this to Ern. Select a channel then go, image - adjust - invert, Then go filter stylize find edges & have a look at each cannel that way it will show the out lines of each colour. Cool!!!!!! :cheers: Ray

Ray, Yep, interesting. I'll post a crop of the 9 deg banding (and an enhanced contrast version) on my site shortly and I'll put a link here.
So far I have only found references on the net to SOLAR 9 deg halos and they call them 'exceedingly rare' or 'very rare'. I suspect I have something even more rare here, this being a LUNAR 9 deg halo. Gee, golly gosh !
I didn't see it visually at the time, being very faint but the camera can see things better than human 'Parfoval Vision'.

Just occurred to me that the eliptical distortions are likely to be due to the halo rings being off centre in the frame and using a wide angle lens (35-105 zoom lens set at 35mm).

Good thinking Ern You mite be right with the lens thing, that would bend things around a bit. :rolleyes: Haven’t been to your site for a while until just then. “Awesome stuff” great work. :cheers: Ray
