Glowing UFO's / UFO fireball's9 red-orange spheres witnessed by two people flying overhead from northwest to northeast.Went to the roof of house around 22:30. There wasn't any considerable wind. The first thing that caught my eye was a glowing sphere coming from northwest and disappearing into a patch of clouds at northeast.7 or 8 more followed it with 1 minute interval, following almost the same path but with varying speeds and altitudes. Their motion was steady and were about half a mile away.The objects in question glowed like a street light lamp and moved without a sound.The ones to see it were me and a neighbour, none had a mobile/camera and couldn't capture any picture,though on searching similar ufo sightings, they closely resembled the ufo fireball phenomenon.During the passing of this 'fleet' 5/6 jets passed southeast to southwest, but they couldn't possibly be chasing the objects.Could not have been helicopters, or any other thing known to us.
