5 large lights hovered above Ogden, Utah, before disappearing one by one.So at this time of year in Eden, it's still light outside, but the sun has gone under the mountains, so it's brightest around the rims of the mountains and fades darker as it gets further from the sun. Basically dusk. This type of lighting makes it very easy to see airplanes that typically fly over Ogden, because of the nearby SLC International Airport.I had just walked upstairs and sat on my bed, and I have a direct view of the mountains separating Ogden and Eden (Eden being where I was.) There was a plane flying right over the North Ogden Divide, so I looked up from my laptop for a second to look at it for a moment. It was then that I noticed a strange formation of lights to the right of the plane.There were 5 lights, each one about a half of the size of the plane. They were in a slightly curved formation. Three of them were in a straight line, and there were two slightly lower than the others on either side of the three. It was so large I feel like it spanned about a mile, because it hovered over an entire mountain peak. Each dot was completely unmoving. The color of each dot was indescribable, and I'd never seen the color before. At a glance it was white with a reddish hue, but then it was also blue or purple if you looked again. It was as if it was all of those colors at once.Within a minute of me spotting it, it started disappearing one light by one, before it was gone completely.I'm not sure if it was a single craft or 5, because it was only seen as multiple lights. It was very bold and I noticed it the moment I looked up. It was just so bright and bold that I was surprised I wasn’t getting fearful texts from my friends and news stories breaking out everywhere.
