3 lights in a triangle shape over a few housesA few minutes before 1:00 am, I exited my house and went next door to my apartment to reheat some dinner, as I am redoing my kitchen and use the apartment to cook. Around 10 minutes after 1:00 am, I was making my way back up to the house to eat, when I looked across the small downtown area and saw a trio of lights above a house and some trees on the top of the eastern hill. I paused for a few seconds trying to make out what I was seeing as I have lived in this house for over three years and do not recall seeing the light before.Since I live on the smaller hill on the western side of the city we do experience a fair amount of fog, as it was slightly foggy on this night so I was unable to see any craft, just the three lights in a triangle pattern.After I ate, my dog started to whine, so I took him out. This was at least 15 minutes later, and possibly 20 minutes. I took him to the spot he prefers and looked across to the lights again. At this point I saw what I can only explain as a shimmer. The rear most light shimmered as if someone put a fine cloth in front of it. This happened at least twice as I looked away as my dog started growling. He was also looking across to the area of the lights.This part becomes a little odd for me as I just wanted to get back inside and return to playing a game online. I paused at the door and looked at the light one last time saw only the back light shimmer one more time and I went inside. I thought as I went in the door I was going to get my binoculars and see if I can see anything, but I just didn't feel like it.The next day as I had made my way back up to the house after eating breakfast I paused and looked across to the hill on the other side of town, no more than half a mile away and maybe only one quarter of a mile, I did not see the new cell phone tower that I was sure had been installed in that area, or at least that is what I felt I had saw the previous night.The light, from my estimate was about 50-75 feet above the house and didn't move during the 15-20 minutes that the light was there
