-Removed-If it was not moving, it was definitely NOT the space station. The space station moves fast (I saw it a few times). And no satellite in geostationary orbit can be seen from earth with naked eye.
If the object is still there it is probably Jupiter. As I said before look again on september 2 about an hour or two after sunset. Jupiter will be below the moon and to the right, so you can identify it.
If you want to see the space station I will tell you when and where you can see it from London.

Jebus..it was frickin mars ok?
Mars' orbit is bringing it closer to earth than usual this august. It's nothing unusual, it happens every so often. Look it up.
There is even a hoax about it. Read more.

In august 2009 it was impossible to see mars in the east in the early evening hours. And even when it did rise, its magnitude was about 1.0 - nothing spectacular.
