Unexplainable bright pulsating yellow-orange object hovering and then flying away at a high rate of speed.

I was putting my son to sleep when I noticed a bright yellow-orange ball of pulsating light floating over the back treetops.  Hovered for sometime and then sped up towards leftward direction.  As it sped up the ball of light disappeared and ?changed into flickering lights - appeared to be multiple objects flickering red, blue , white very very quickly ( not like the steady plane lights at night).  It crossed the skyline within seconds. I’m a physician by practice.  This was not natural. I have security camera footage vouching for the 1st half of the story ( the object left the field of the camera).
