Sitting in the hot tub about 8:30pm, Wed Feb. 11, 2015. Noticed a large, unusual 'star' of amber color. Twp Lemoore Naval Air Station jets came by as they do at this time, making a loop travelling East, then West- a familiar pattern. Before turning, they traveled farther East than usual. The amber 'star' suddenly flashed three times, moved about two degrees East, then stopped. It waited about two seconds, flashed again, and flew quickly East and disappeared in an instant.The NAS jets turned West and resumed their usual route.I came into the house, and told my wife about seeing a genuine UFO!She had seen one in 2005, early spring, in about the same place in the sky. This was different, as she said it had the shape of a boomerang. She had been in the hot tub, staring at the incredibly clear night sky- unusual for us. It was during a lunar eclipse, and the sky was dark. As she watched, a shape went across the sky, from West travelling East, at about 45 degrees. The shape was obvious only due to the silouette of the shape obscuring the stars behind it. As it crossed the sky, the > shape allowed the stars to shine within the hollow of the mid-structure- so she knew it wasn't a solid triangle shape. She said it was enormous and completely silent, with no reflective or metallic quality. It took about 5 seconds to cross the full path of sight and was gone.She had called the local astronomy director at the observatory, but he did not return her call.
