I was working at the public pool. there was a pool party going on, but we were taking a break due to lightning. i was sitting on a bench, facing south, when i looked up from my phone to see an orb with pulsating red light flying away from me. it looked to be flying lower than airplanes tend to do, and as i watched, i saw it move suddenly to the west, without banking or turning. it didn't move terribly fast, but that turn struck me as very unusual. i watched it until i lost sight of it behind the trees, then i filmed it on my phone as it reappeared from behind the trees and flew towards the lightning. it eventually flew behind a building, and i lost sight of it.
