5 UFO's 2 1 2 form over Nottingham United Kingdom

Time 16:00cumulus nimbus in a blue sky cloud at 3500ft checked local weather from behind a cloud at 11:00 o'clock high five unidentified objects, orbs like caught the sun flying in symmetrical formation 2 front one centre two back like playing card format travelling east to west at incredible speed fleeting glimpse probably 1/2 to 3/4 of a second - in that time travelled estimated 8-10 miles across the sky very bright like mirrors reflecting the sun suspect higher than high level ice clouds also present in sky as when the sun stopped reflecting on the orbs they were no longer visible the objects were in the general direction of the sun but lower in the sky. Very bright and absolutely not balloons planes, swamp gas or anything I have seen before. Incredible speed no sound checked on plane app no traffic in the vicinity nearest commercial aircraft over derby 15 miles away, could see this at the time far south west leaving vapour trail definitely not that plane. Hope that's gives enough detail
