Heres the website Louise ... It was Soulandy who put me on to it a few months ago , cheers
Change your location but it doesnt vary much over UK. I too watched it nearly ever night last week after sunset. Bright light moving across the sky , brighter than a star so perfectly visible with the naked eye. Travels at 17500mph , over 200miles up in low orbit.
The only thing is.. it has to be OVER 40 degrees to see it, so youve missed your chance for a while Louise , (it was 70 degrees last week, which is almost overhead. The next few nights it is too low for the sun below the horizon to light it up ( thats what makes it visible).
Nasa will update that website in a day or two so fingers crossed itll be over 40 degrees again soon .
