I was at the office and after having lunch me and a coworker decided to go up to the 2 story building's roof to try to take some pictures or video of a lighting storm that was taking place. While trying to catch a good video of the lightnings with my cellphone's camera I spotted the bright orb hovering very high and very far away in the sky although still under the clouds lines. We thought about what it might be for a while and made a couple of videos but after about 30-40 minutes it started to move father away and as we had to go back to work anyways, that was it.
