Walking South on Upland Avenue a bright orange/red light appeared in the distance, it came closer over the Millmont area of Reading, PA and got brighter until it lit a large area of the sky, it made no sound.I noticed the light due to the vivid color and intense brightness. Also, it was a hazy night, and the intense light illuminated a massive oval area of haze around the central circle of extremely bright light as it neared.Initially I thought the light was a medical helicopter from a nearby hospital, however, the color was wrong and it was silent. The hospital is maybe a mile north of this event.The jagged edge, circular light was slowly heading North, maybe 500 feet above the ground, it got larger and brighter as it got closer. At its closest, maybe a half mile away, it began moving left, right, up and down in a slow, erratic way. Then it began descending in a slow, smooth arc to the East, until it disappeared as it neared the house/tree top level. The entire event took only a couple of minutes.I was very excited by the slow moving light, as I had never viewed anything like it before. When it was over, I was perplexed by what I just saw. I still have no explanation for the intense, nearby and quiet light.The light simply disappeared, I do not know if it navigated behind something, or went out. I scanned the area for maybe 15 minutes, and it never appeared again. It was really a spectacular sight, which is why I am writing this. Sadly, I did not think to take pictures, as I'm older, and forget my phone has a camera in it now.
