What is in the sky?

[shortstuffO3]

Has anyone out there been seeing an unusual thing in the sky around dusk. It is in the western sky and I have seen it 2 nights in a row right at dusk. It is like a big ball of light (it almost looks like a big planet), but it gets smaller and smaller until finally it disappears. It then will come back out maybe 2 more times and then I never see it again. It cannot be an airplane, because there was no clouds for it to go behind and I watched a jet coming from the west and it did not disappear once! So if any one has an idea, please help me. Thanks!

Where are you? You write "airplane" rather than "aeroplane" - are you in the US?

Has any cattle been going missing recently? ;)

I am in the lower part of Pennsylvania in the US right where Pennsylvania, Maryland, and West Virginia almost touch. And I don't know about the cattle.

Is it a Satellite? ... don't know what Geo-stationary ones you have in your area?

I have no idea what the thing is, like I said it is there big and bright and then it fades and disappears! It is pretty weird. I think that I am going to try to record it tonight so that you all can see it, then I will post the URL for the video on here. So keep checking! =) Thanks for all your ideas.

Possibly a sattelite! I'm in southern England and around this time we can sit in our garden and watch the sattelites - look up at the sky at the stars and after a while you can spot them moving very fast across the sky - perhaps your seeing one 'end on' as it were.

Is it the moon? does it disappear when you close your eyes?
Not sure why it gets smaller though
