I was driving and I saw some lights between the trees. I thought they were some kind of Christmas lights though pretty big for that. As the car moved I realized there were more of them and when I turn the curb it was clear that they were in the middle of the sky but it was overcast and they appear and desappear probably due to the moving clouds. Three of the lights were smaller or were higher and were separate from the rest of the group formed by around seven lights. This group keep a constellation kind of shape. I stop the car to see if they were making any noise like a helicopter but there was total silence. They stay like that for a few minutes. I was trying to take a picture with my cell phone but the streets lights were too bright and nothing came out. Then, some of the lights starting to move, two of them may have fussed but I am not sure. Them they disappear probably they went higher than the clouds.
