A BIG YELLOW BRILLIANT BALL FOLLOWED BY MANY OTHERS COLORFULL SMALL LIGHTS IN V FORMATION FLIGHT

I was 15 years old when it happens. I came into my house around 10:00PM and, wwhen I look toward the stone quarry, near to my mother's house I saw one yellow big  brilliant ball flying from north to south. Following, many others brilliant lights, in full changing colors and in various sizes. There was a calm deep dark night, without clouds. The lights moved on the sky in V formation flight, slowly. No sound I heard. At this moment, I feel very impressed and started to shout to my mother, she was sleeping inside the house as long as the lights passing by. When she comes, the vision already was going, disappearing in the horizon. I was very nervous at the end of this experience.
In the next day, the newspapers noticed a man who saw with binocullars in a near city called SERRA, nearby, VITÓRIA, capital city of ESPÍRITO SANTO state. The most important TV Journal of the Country also noticed this event in the next day, reporting the route from the south BAHIA state to ESPÍRITO SANTO
Date is approximate.  We have assigned an arbitrary date in the Brazilian winter of 1976 so that the report sorts to that year and season.  PD
