Bear in mind it can be extremely difficult to assess the range of an unusual object from you.
I recently saw a greenish object travelling north east to the north west of my control tower; to me it looked about 10000 ft up and maybe 5 miles away, but on reporting it to the 'space debris' man at the British Astronomical Society, he told me that triangulation with other reports indicated it was actually over the north atlantic over 200 miles away and about 150 miles up!
