I was driving s/sw down iturregui avenue in carolina, pr at around 12:45pm on a clear afternoon. i saw a roughly egg or saucer shaped thing hovering in the clear, blue skies over the san jose lake (or lagoon). the object was silver or chrome colored, like solid mercury. incredibly reflective, to the point that it was so bright that i couldn't really tell what part of it looked like. i only say it's egg colored from the parts of it that i could see clearly. as far as i can tell, it was hovering over the lake near the airport and teodoro moscoso bridge. i lost sight of it while driving a few times behind some trees, but i'd find it again in the same position when i looked back after getting a clear line of sight once again. i lost sight of it one final time behind the trees and when i got to a place where i had a clear view and a place to stop the car, i couldn't find it anymore. i didn't manage to see if it left or disappeared or anything. i just couldn't find it anymore where i'd been seeing it for the few minutes it was there. usually, you see a lot of airplanes landing around the area, so i had to look twice before i realized this was no plane or helicopter. honestly, i don't really know what to make of it or what it was, but it was very strange. didn't really know if i was even going to report it, because i don't know ehat to make of it. maybe you can shed some light on it.
