Curious as to what I did see last nite....Posted By Jim Nelson |
Any bright star, if very low in the sky, will show color shifts (assuming what I'm thinking of matches what you're describing) due to atmospheric refraction effects. Basically, the atmosphere acts as a wavering, changing prism so that different colors can be seen. I'd guess it was the star Arcturus, which is bright and which would have been close to setting in the WNW shortly after dark.
