Possible UFO

Eight or seven months ago, I was in my town, in a procession, I went ahead a little to rest; after a while I look up to the sky and I see a blinking green light point (I think it blinked every 1 second), I had no point of reference but the object felt very high up (at the height of the clouds), I will describe what happened: -It moved westward at a speed that looked like an airplane. -It disappeared and then I saw it move to the east. -It made a sharp turn and returned to the west, disappearing and appearing behind the clouds. -It returned to the site of the first sighting and stood still for a moment. -Disappeared -Appeared, advanced slowly to the east and then accelerated very fast(however I could see it), did not finish the journey(there was a bar I was waiting outside that obstructed my view to the east, the object did not reach behind the bar, out of my field of view) and disappeared.

Points to note: -It was at night, although I was in the procession, they were not playing music and there was almost no one where I was. -It happened during holy week, in March, and I remember that at that time it was said that a “mother ship” was sending UFOs to earth, many people had sightings or contacts at that time. Theories: -It could have been an airplane (flashing green light that lasted the entire sighting,speed at the beginning of the event) but how is it going to make such a sharp turn? And the tremendous acceleration at the end? -A helicopter: it would explain the curves, however, the object was faster and no noise was perceptible
