Was outside my house putting trash can up around 6pm (was dark outside) and saw something over the Mississippi River catch my eye, saw small orange orbs appear in side by side formation then disappear one then the other. Would reappear in different parts of the sky then disappear. At one point they appeared one after another almost in attempting to making a V symbol then slowly disappeared one after another. This is the second time I have witnessed such a thing. In June of 2014, in the same location over the Mississippi River, I witnessed the same thing happen. I looked on this site a few days after I saw it and noticed someone else in my same town witnessed the same thing that year. I have no idea what these orange orbs could be?
