Bright glowing, spherical, balls of light that dart around the sky with silence an super speed an gracefulnessWe have observed for the past three nights. Times vary between 10 to 25 minutes They are bright glowing orange, appear to be spherical in shape, appear out of nowhere an disappear without warning. No sound, very calm outside. They have sat in a straight line, they move in ways I have never seen an aircraft move before light will dull down an can range in color then will move all over the place then stop hold positions an glow bright again and will continue this type of behavior for some time. When they go, it's almost a streak across the sky like a shooting star will do but u have to b paying very close attention or u will not see this.
