Black unidentified orb which flashed red (though appears black/metallic in video) moving smoothly East.

After seeing a different black sphere-shaped UFO moving North 8 days prior, I made it a priority to start walking with my phone. Sure enough, 8 days later I looked up and spotted a fast East-moving black sphere that I could not identify. Clearly not a drone, plane, helicopter. Object flashed fully red a few times, before disappearing into the distance. No clue what it couldve been. This one was clearly spherical, whereas the one 8 days prior seemed mostly spherical, but with additional detail around the sphere. Video does not show the red flashes, but to my naked eye it was clearly doing so.
