A weird, rainbow-like phenomena gave us
three suns today, here in Oslo. See here:

... The newspaper text is norwegian, but the image speaks for itself!

Very cool sun dogs! We recently had a blood red sun-pillar, but unfortunately our camera isn't equipt to take the picture....

Agreed, nice dogs (parhelia sp?)...We get them in New England, usually they aren't as bright. Not as much ice as in those Norwegian skies
.
This site has some good info on atmospheric phenomena
http://hyperphysics.phy-astr.gsu.edu/hbase/atmos/atmoscon.html#c1
BTW, the main site is an excellent primer in many aspects of the physical sciences... Check it out.

A few months ago we had here a similar phenomena really gigantic around the sun:

I saw what i like to call a "Sun Bow". It was like the sun was stretched out, then bent. it was cool.

I was having a mental block this morning when I posted above. I couldn't remember the link below to a really cool site on atmospheric phenoms...
http://www.sundog.clara.co.uk/atoptics/phenom.htm
Go into ICE HALOS and download the free HaloSim3 (no Hunter, not that Halo
)...
It creates simulations by accurately tracing up to several million light rays through mathematical models of ice crystals.
It's fun to play with (well if you're a bit geeky like me it's fun.)
Also grab the IRIS software under WATER DROPLETS for corona simulations like ElChristou's pic.

Were the other two "suns" bright enough to cast shadows?

We see them here in Ontario quite a few times. Usually though, because they occur when there are clouds of ice crystals present, the sunlight is difussed so much that you get only vague shadows. I have never seen a triple-shadow effect. However, I have never seen sun-dogs as bright as the on one pictured - so ... maybe you can.

One of my favorite websites.
One section that I find interesting is the description of sundogs and atmospheric phenomena on other planets.
