A bright white orb was glowing and moving north but then would hesitate and stop and then move again. It appeared at one point to split into different lights, green and blue, even some red, and then they switched sides as it moved overhead and continued north. At the same time to the east- there was a high flying pulsating orb moving at a high rate of speed to the south. It was considerably higher and could have been a plane in the clouds, we could not tell. The only reason we suspected it was not was because it was moving so much faster than normal jets we see at night- we live by Palm Beach Intl airport and see a lot of air traffic.
