ufo amber globe

i have witnessed at approx 11.15pm on 21/02/09 an orange globe about the size of an amber traffic light travelling quite fast whilst looking out of my brothers kitchen window, i went outside to check that i wasnt seeing things and watched it for about 1 minute until it was too far away to see.  this was too fast for a normal aeroplane and the light was also too big and it wasnt flashing, there was no sound.  i was shaking a bit and so decided to look for a website like this to see if anyone else out there has witnessed anything like this.
