Was late afternoon, I was returning from office in SENAC, It was about 17h30 summer time, nearby my home, i just saw a ascending yellow-orange light in fast speed to sky, it was not followed by anything or anybody with or without plans or other object, nothing was near the object that i saw, the sky was perfectly clear!I know that the object i saw perhaps was nothing for you people, but i know that was an OVNI Yellow-Orange Crystal.
