At about 10:30 pm, I opened the door to let my cat in. The sky was very clear, and I was admiring the stars. As I was about to go back into the house, I noticed five round dim pinkish lights floating in the sky coming from the east. I couldn't tell how high the lights were, but as they flew above me, I could see that they were attached to a triangular frame. It made a very slight humming sound, and passed by fairly quickly. It didn't move like a drone. I didn't have time to get my phone and take a picture
