The object has been seen by both my husband and me two times, at night. The object is a glowing crescent, the color of the sodium (Na) "D" line. It hovered over Byrd Spring Lake for about 15 minutes on June 4. Last night it emitted extremely bright yellow flashes that lit up the lake and the inside of our house. The bright yellow flashes were not the orange of the sodium spectrum. There is nothing behind the lake for several miles. There is a hunting preserve, followed forests on the Redstone Arsenal. We heard no noise, and the object was stationary. It has disappeared, as if the lights were turned off, and then returned. It is shaped like a crescent.
