I was investigating storm drain locations for a drainage study I was doing for work when I found this object in the sky while scrolling through the Google Earth Street View. You can find the object in Google Earth by going to the cul-de-sac (end) of Wolverton Road in Baltimore County, Maryland 21234 and zooming down to street view. Slowly scrolling out of the cul-de-sac you will see the object in the sky for one frame. Scrolling one frame forward or backward from the object frame and the object disappears. It looks like a disc shaped object.
