9 spheres of light, appeared on the sky at 9 pm. They flew like birds, without a straight pathing. and very unpredictably and would come close and apart from each other randomly. They would change colors varying from green, yellow, blue, white and red. The lights at one time randomly formed shape while some would be in a triangle while the other form a pentagon for a few seconds then would come apart and become random again. They crossed the sky quite quickly then they flew higher until I lost sight of them.
