there were at least 7 orange coloured pulsating round sphere shaped objects flying in a south easterly direction one behind the other but not of equel distance between each other. there were 2 spheres that were someway behind the main formation. i would estimate that they were at least 1500ft high, i could hear no engine noise at all. the light from the objects pulsated and changed colour from blue ,yellow green etc. the thing that really spooked me was that every one of the objects started to dim until all the light had gone.

they all kept the same speed besides the two who were lagging behind who increased speed to catch up with the rest0

only that it would be strange to see a large formation of aircraft at that time of night, even though i live near to an airport. also the strange colours which dimmed out until there was no light at all, the abscence of sound was also a factor.
