Visibility III / V
15.5. 2022 around 23:42 1-2s lasting flash in the sky in a south-southeast direction. Height with a fist length of about 40 degrees. The brightness was estimated to be about 2-3 times brighter than Venus at its brightest, which I have seen. Checked flight Radar, when the suspicion that the aircraft landing lights had flashed, no aircraft was found. No movement was observed during that time. No sound, and no fading plane lights. Attached are pictures of the location and direction of observation, as well as a flightradar image of the aircraft.
