UFO Sighting in Woodbury, Minnesota on July 28th 2016 – it looked like a pair of two orbs with a halo around the pair

I had just gotten home for the evening and was taking the puppy outside to do her business. At this time there was still twilight. After I had walked back something caught my eye just above the trees. I said to myself, "hey what is that"? I ruled out the possibility of it being an airplane. In the back of my mind I was thinking drone. I then noticed it was two magenta orbs paired together with a little bit of space between the two (golfball sized). I quickly ruled out all other possibilities realizing that what I saw may genuinely be a UFO. I felt intrigued, curious, afraid, excited. It was silently hovering about 10-20 feet above the tree line and about less than a mile away from my point of view. It lasted about 15 seconds and then moved away from it's hovering position at the same rate of speed you would turn off a dimmer switch.
