Last evening i was watching the dragon 9 launch at 7:27 pm and to the left of it, i spotted what i thought was an aircraft. i watched it and it did not move. it had a row of blinking lights of white red and green. this remained stationary for a good half hour before i went back inside. i tried photographing it and tried binoculars but never got a good view. several aircraft were in the sky well below it. did anyone else spot this?
