Red, white and blue flashing lights.I saw a big bright object that was circular shaped. It flashed very bright lights of white, red and blue. It was stationary.Before I seen it, I heard 4 weird booms, 10 minutes later I go to let my cats in and out of the corner of my eye I saw the white, red, and blue flashing lights. I thought that maybe it was a planet but it looked too big to be a planet, and it had very distinct flashes of blue and red.I kept an eye on it for 2 hours. From 20:00 to 22:00. At 23:00 it was gone. At 00:00 while hiding easter eggs I looked out again and saw the red, white and blue lights again but it was now moving about the speed of a plane. It almost looked like the the lights were circulating around the rim of the craft as if possibly, it was a saucer.I had my bf come look. He said it was a plane but as we watched, it slowed down to a stop for about 30 seconds hovering slightly left to right and then slowly started to move at plane speed again.
