7 or so bright orbs traveling in formation and as they got to the big dipper changed into V-shape and disappeared.

My son says Mom, what’s that and I look up to see about 7 round white orb looking objects traveling in a straight line formation but, as they approach the big dipper "handle", they changed formation into almost a V-shape, and they disappeared. No noise, no wings, no smoke. I tried to get my phone one but, they were gone. It would be easier to draw a picture of what I saw to explain it better.
I tried to check satellite websites for any launches (I've seen the satellites in the sky when they launch, and it was nothing like that).  I tried to check for any possible military training because we live next to a small coast guard base and 3hrs away from Joint Base Lewis McCord military base but, I couldn't find anything saying that they had training that night. Also, I've seen/heard a lot of military aircraft fly by, and these were completely silent. If I wasn't looking up, I would have completely missed them. The only noise was from other people on the street saying, “Oh my god, what is that!”.
I waited to report this because I assumed an article would come out saying they had satellites, trainings, or something to explain what I saw. Obviously, I'm no expert but, I know what I saw. It's been a week and I'm still checking for more information. I'm sure you have way more resources than I do to confirm any sort of explanation and I would love to learn your conclusion!
