This is because of scintillation ("Twinkling") as the light passes through the atmosphere of the Earth. As the air moves in and out, the starlight is refracted, often different colors in different directions. Because of this "chromatic abberation," stars can appear to change colors when they are twinkling strongly.

Ok. I got it. Just for my own piece of mind...you don't think it's a geosync satellite because "of the reasons" you stated earlier. What exactly are those again?
PS is it dark there yet? Is it out yet?

However, this only happens to 4 stars, and many times the other three can't be seen, so it can't just be because of atmospheric conditions, there must be something to these stars that also make them look that way meanwhile other stars all look in just one color.

You mean "for your own peace of mind". ;P
Geosync satellites do not twinkle, and do not change colors.
It is most probalby Sirius that he is seeing, and the movement is just an optical illusion from looking at one object for too long.

Sirius is supposed to be the brightest star in the sky, and it has been worshipped by many ancient civilizations.
All evidence tells me it is more probably Sirius, however, I have been able to see it at times when it shouldn't be seen. It is supposed to set after the Sun and rises before the Sun, but I have seen it well into the evening hours.
Also Sirius is supposed to be the only star that shines in different colors, but what about the other three which are smaller but also change colors?edit on 17-11-2010 by ElectricUniverse because: error

BTW, as to you seen it move, it is more probably an optical illusion. If you look at an object for too long, you will see objects close by move, but it is only an optical illusion, they are not really moving differently from other stellar objects.

Where in the night sky do you see it?
To this day I still look at the stars and I haven't seen anything new.

Thanks for the advice, I am fully aware of this however and can tell the difference between what could perhaps be conceived as movement and precise motions that have direction.
I don't really think that you are in the position to tell me what I'm seeing and what I'm not seeing to be perfectly honest.

Obviously noone here is in a position to tell you much of anything without you not liking their tone, etc. If you opened this thread to make an announcement...you have succeeded. For a moment there I thought you were looking for answers or quite possibly the truth. Your posts betray an altogether different agenda.
Good luck.

I suggest you accept his theory on the condition he provides irrefutable evidence to support his contention.
