I was out around 11:25 observing the sky, and had turned around heading to the house when out of no where an appearance of a large craft appeared at the SOUTH of my woods , and I only observed the back of the craft, it initiated lights on very bright on the back of the craft and initiated forward lights on both sides, but they did not light up the ground or woods below just brightness on the craft and then from right to left red light back and forth. The lights were white with a tinged of yellow.The craft was heading SOUTH toward the knobs, and then blipped out and was gone.I want to point out that the lights were very bright and it made it hard to adjust my vision to see the rest of the craft.I measure this morning the length of the rear end of the craft of what I could see and it was in the measurement of 90 to 100 feet across.
