Dozen flying sparks in a birds flock formation flying across eachother.Aprox. a dozen flying dots were noticed while observing a moon through a binoculars. The ir color was fade orange and the size of the dots was the size of a sattelite or a distant, not very bright star. Dots formed some sort of a group; like a squadron but not a plane squadron; it was like like a birds flock. The movement was very similar to the birds' (the flock is moving in one direction with barely winding on the sky, but the birds are flying across eachother). The movement (style) of the objects could also be compared with the sparks lifting above the fire; gentle without a strain and it almost seemed it was a play of catch me if you can. There were no fire on the ground and it had to bee pretty high above the sky although it didn't seemed it was in space; it had to be closer than the sattelites circumferences are. There was no sound or noise. The dots were lost behind the house blocks and were faded out by the citiy's lightpollution. (direction WEST, we also noticed a couple of falling stars the same hour but in the opposite direction!)
