Red Flourescent Ball 19:26 GMT moving through 140 degrees of arc in less than 30 seconds

Ely, Cambs, England

My wife and I have just been to post a late Christmas card to a neighbour in the next street.  We both saw a phosphourous looking red/orange ball rising in the west and travelling at meteor like speed passing through the whole of the visible horizon disappearing in the East only 25 or so seconds later.  The intensity of the ball was constant but it did shift from red to amber and back.
