While standing on my apartment's balcony while smoking, I was gazing the sky randomly. At one point a flash of light attracted my attention and saw a moving "star". At first it was like a normal small star but while watching the light got very bright like the North star. This event took no longer then 5 seconds, then the light went dimmer until vanished from my line of sight.I don't know exactly what I saw but as I know a landing light of an airplane is only used when landing and this did not have the airport trajectory. And I guess that the landing light is not week at first then increases in intensity then goes dimmer.
