I was standing at my back door smoking. i glanced over to my right and in the field at the back of my house saw 2 lights blink on. i first thought they were sheeps eyes but there was no light source to cause that. plus, they looked rather light an old fashioned torch that had flat batteries. the ‘eyes’ were on for perhaps 3 seconds then they went out/off. approx 30 seconds later the lights came back on but much, much brighter. they started to rotate quickly and rise up. they rose to about 50 feet then briefly followed the fence line. when they got close to a tall tree, the craft rose up above the tree. hovered there for perhaps 10 seconds then shot up and accelerated at an incredible speed due east and i lost sight of the object.
