Sphere found hovering above camp councilors.

My mom was in camp in what is now Pocono Pines, PA.  Late at night, standing at camp, looking over the lake.  The suspected UFO came out of no where, over her and her friends. She said it made no noise it just hovered over them.  It was like a sphere with white and red top, she says it reminded her of a police light.  The separate camp across the lake mentioned that they saw said UFO, flying over them while they were in a canoe.  My mom says it was super odd that they didn’t react, nobody was scared even though it hovered over them for a few minutes.  Nobody talked about it later as well.
Witness indicates that the date of the sighting is approximate.  PD
