i looked up at the stars as it was getting darker. as i did i noticed a small point of light moving high across the sky. as i watched it arch across the sky it did something totally unexpected, without stopping it reversed course and as it did so it also came downwards until it couvered two house tops. yht object was bright white with a slightly darker shade of white in its center. the object remained for approximately 5 minutes and then just suddenly dissapered back into the sky.
