I went into my yard to look at the moon, it is a very clear night. i could see some planes flying in the distance and over head, then out of no where this object that looked like a triangle but was more shaped like a stupa passed over my head and it kind of looked like it was revovling and i fumbled for my camera and managed to get one picture. then it just keep going south east and just tapered out of existance.
