Bright light fairly low in the dark sky around 4:30am. I was looking out of a window in the district or Barrio La Loma just outside the village of Albuñuelas where I am on holiday from the UK. The object seemed low enough for me to hear its engine if it was a helicopter or a plane but it was silent. It didn't move like an aeroplane because it kept stopping, hovering and zigzagging. At one point it shot extremely fast from one spot to another before slowly moving away over a mountain and eventually disappeared out of sight. All the while there was no sound at all. This is a very remote part of the country so I am surprised when I couldn't hear the sound of an engine especially when it could have only been a helicopter if it wasn't an UFO due to how it was moving in the air. I've never seen anything that I would have described as an UFO until now
