My daughter and i have been going to the top of our parking garage to open up the sunroof and star gaze which is something we like to do when it's clear. i saw a arrowhead shaped or boomerang ufo flying at a high altitude with constant blue/white lights fly directly over us and then disappear behind cloud cover. it was headed from the south going north. it had to be huge! as it was so far above us. it seemed dimly lit, but i believe that was because of the distance. my teenage daughter didn't see it as she had her head buried in her phone and wasn't able to grab her glasses in time to view it.
