At 7PM PST I went out to the front of the house for a smoke. I noticed very bright red orange lights in the Eastern sky. The leading lights appeared to be in a formation that resembled the big dipper and were followed by multiple other lights. These had no formation but some were in groups of three, others were single objects. They kept coming into view from the East heading North.(They turned toward the North) I called my wife to come outside quick. She came out and witnessed the very strange show in the sky. There must have been over 20 of these lights and as they turned North they got dimmer. Some of the trailing lights descended and a few seemed to stand still and others passed them. We have no idea what they could have been .They weren't flares or lanterns or drones. They seemed too big to be any of those. We are totally at a loss. I would think that an aerial display of this duration and size must have been noticed by others in the area of Henderson.
