At first i was looking into the sky towards the west from my backyard patio at 22:37 and saw a bright object moving sw with pulsating a bright white light. then it disappeared and reappeared travelling in the opposite direction ne, and it moved upward vertically and disappeared while pulsating. i was very excited and asked it to show itself for my wife to see, but my wife left. i then re-entered the house and just a moment later, i went out on the backward patio again and there it was again showing up pulsating light like never before. i waved and got more response by light pulsation.
