I live in a city called porto alegre, in south america, brazil, where i live it is possible to see ufo every day, yes i am sure of that, they are all day in the skies, with lights flashing red green blue and have a which especially has a strong white light but seems artificially produced that on one day i saw the others with different flashing lights join this ball of white light as if they entered into the ball of white light, move with an absurd speed , sometimes standing as if they were in sync with a ufo at every point on the horizon as if they formed a type of arithmetic symbol, such as a triangle or giant hexagon, i have also seen them moving and moving to leave a type of green trail in the sky as if it were a leftover of energy but i could only see it for a moment of seconds, as if it were really energy, i do not know what happens in this city, i do not know if it is normal to have ufos every day in a locality and but unfortunately i do not have a good camera to record, i only have the camera of my cell phone that is not very good for the record and i can not record perfectly, i hoped that someone from mufon could help or come and record it in video or photos. sorry for the bad translation.
