I was at the Titicaca lake in the shores of Carabuco Town, taking night pictures of the lake and the stars. I havent noticed it until I sow the pictures.I thought inmediatly it was a big UFO I've seen one similar aswell in Titicaca lake but in other side of it. you can notice the difference between stars and directed lightsit appears moves a bit and then dissapear.It is always a bit different being in the lake, in those remote places people from the town and indigens talk about it as a common event.
