I was looking up at the sky since there are animal traps on my roof to catch the flying squirrels in my attic. the moment i looked up to view the trap, i saw come over my house a completely white object with 2 shapes to it. one end was rectangular, and one end was rounded. the sky was blue with no clouds. this object sped up a little, then slowed down, the sped up a little, then slowed down and then stopped. it then disappeared. the total time span was about 15 seconds. there was absolutely no sound.
