It was arround the six am in the month of april of 1989 year. i left my girlfriend in her house and was returning to mine. i was walking from plaza de la constitución to paseo de las palmeras and in front of me was the "lonja" (fish market) and it was closed. now there are a seaside park ( parque maritimo), but it was not in 1989 and it only had the harbor empty places. then i was walking and i can see the harbor and the fish market in front of me. firstly i saw a light and i though that was the light up of the major pole of a ship going out of the harbor. the fish market was closed and the light began a ascendent trajectory. i know all the lights of the harbor and the gibraltar strain and it did confused me inmediately and it was for me very strange because all the lights of the ships remain in a horizontal trajectory. that light was like hidden, masked; it was trying to go unnoticed. it could be 2-4 meters and it was 200-300 from me. but i began to walk quickly to the light for see more exactly what it was. the single light changed inmediately, now it was a diamond with amazing and hipnotizing white color. i cannot define the light exactly, it was amazing, only can use the word diamond for define it. it had inteligence because it was spying in the harbor of ceuta, and i discovered it and i knew that i discovered it. why? because it change inmediately the direction from ne to south and the ascendent more strong and dissapeared behind a long building.
