Novice here I'm afraid, so excuse my ignorance! I live in Feock, Cornwall and for the past few nights I've seen a bright object passing high in the western sky. It takes about twenty minutes to traverse the window where I'm sitting, so quite fast. I thought it must be the ISS but that doesn't pass over here apparently. I've checked with a satellite times web site but found nothing. What could it be? Many thanks!
