several threads have debated this one, alot of people say Venus, which of course it could be, but venus twinkles green, Jupiter is currently around and we can see it with the naked eye, and jupiter is very very bright but doesn't twinkle
Yes, I first noticed it a few weeks back....maybe around Christmas....I actually stopped to see if it was plane. I got back and immediately did a bit of investigation to find out what it was.
It makes me smile when I see it on a cloudless night :o)
