A V shape of 5 white orbs going south west, changed from a white triangle to a white diamond shape before disappearing

Around 9:40 PM 4 of us saw a white V shaped object going extremely fast from the handle of the Big Dipper constellation and headed south west towards Peavine Peak. The object had 5 faint white orbs in a large V shaped formation that morphed into a diamond shape formation with the 5th orb in the middle of the diamond. It was traveling extremely fast and disappeared within around 6-7 seconds. Between the orbs looked like it was open sky, not a solid object but separate orbs flying in formation. It was in a suburban area but it disappeared in the sky and not beyond the horizon. We’ve seen things similar to this nearly 15 times in the last year, each time with multiple witnesses. The provided images are drawings of what it appeared to be, changing from the V formation to the diamond formation.
