Was driving and a bright flash caught my eye. after looking in the general direction of the flash which was upward from my view of driving i noticed alternating flashed of lights from and oval type object. it was very distinct from left to right. i witnessed this at a stop light for about 30 seconds. once i turned i could no longer see it. my kids were in the car and one tried to take a picture of it. all we got was a light. there were no airplanes in the area or any new cell phone towers.
