UFO Sighting in Annapolis, Maryland on 2017-08-09 21:35:00 - Very bright light coming out of the west then dimmed and disappeared going east

Standing in the driveway in front of my house with my daughter and wife. my daughter noticed it first and asked if it was a plane because it was not blinking. it was very bright white light the size of a round pill, moving at a steady pace out of the west going east. there was no sound before, during or after the sighting. it did not strike me as a plane as it didn’t move as a plan should, something about the pace as it went by. as it moved across the sky it started to dim and then went dark.
