Row of lights moving together silently through the sky

On Tuesday, May 4, 2021, at approximately 9:30pm, my partner and I were outside enjoying a fire in our fire pit when I noticed very strange lights out of the corner of my eye. We both then looked up and saw a row of lights floating through the sky. There were many small lights moving together, all a part of one object silently moving through the sky. The lights were not in an even pattern and were steady as it moved through the sky. My partner and I ran to the front of the house to continue watching it as it moved. It passed over the nearby hill and disappeared into the darkness, as if designed to easily blend in at night.
 My camera on my phone was not strong enough to pick up the lights, but my partner’s phone was. The image does not show the details of all of the little lights as it looks like a more solid ray of light, but the image does show that there may have been more there than what was visible to the eye. In the photo, you can see a difference in the coloring above the lights, as if coming up to a point. This leads me to believe that the lights were along the edge of the object, flat underneath, and domed to a point on the top.
