Ball. Strong green light. Eventually it changed its color to red. Movements not compatible with known aircraft. Initially it looked like a DJI Drone, but in extremely high altitute. Trouble is: it never came down. 90 degrees movements and shifted abruptly in circle movements, 90 degrees, fast and slow when intercepted by a high-powered laser green from land. Disappeared after 15 minutes. If the object returns, I'll let you know. No recording.
