At about 11:45pm on New Years Eve, I what appeared to be 2 orange "orbs" moving from the SE to NW direction, passing directly over my house as I stood in the driveway. I watched as the approached from a distance. At first I thought they were 2 helicopters, but as the got closer I noticed they were flying relatively low (perhaps 700ft?) and there was no sound or any lights to indicate port and starboard. The only light emitted was an orange glow. As they passed over my house, I walked from the driveway to the street and faced the NW to watch them. They appeared to be ascending but as they did, the light faded to a mere dot and then I could no longer see them. They were not moving very fast at all….no erratic movements. Just a moderate, steady pace and what appeared to be a steady climb. They did not seem to move further away from each other. I thought perhaps someone was flying drones. I then noticed more approaching….3. They all flew the! same heading, no erratic movements. More followed. In 3's, except for the second to last wave. There were 5 grouped together, then finally 3 more for a total of 21. The first 2 were from the SE, whereas the remainder seemed to come from a more due-south location, but all ended up passing over my home and headed NW/NNW. I never heard a sound and after passing over the house…maybe 500ft beyond the house, they seemed to just continue to ascend and lose their glow, fading to no light at all. But the lights didn't seem to disappear due to climbing in altitude. They just stopped glowing. I could no longer see them. It was almost like watching lantern light turn extinguish as you turn the knob. Really very strange.
