On my flat balcony. Light to bright then saw some others and kept staring. The object appeared a star or airplane. But then kept changing, not moving and was to big for airplane. I checked flight radar and no airplanes in the area at the moment. At least at that height.Started with white light, then 3 red lights showed up, then disappeared, white light appeared again, with random bright blinking. Afterwards, some orange trail. And again this 3 events randomly during 10min
