At 6:00 am this morning I went into the garden of my house to look at the winter sky that at this time of year in Brazil is always very nice. the sky was still a little dark and many stars could be observed when a small circular ball of yellow light caught my attention. First I thought it could be the beacon of an airplane, but the lack of noise typical of an aircraft and the path that the light was always straight with small but sudden movements to the sides made it clear to me that it could not be a plane. The object followed their path in the sky in absolute silence at a height of approximately 200 meters to go away from my field of vision. i observed it for about 7 minutes
