Despite I’ve no reply to this unusual sky phenomenon I’m simply contemplating if it could possibly be a holographic laser projection carried out by an unknown system utilizing extremely superior laser know-how.

According to physics.stackexchange you may lock the frequency of two lasers to one another, in order one drifts the different follows identically. If you section lock the two lasers, then it is possible for you to to see the interference sample together with your eye.
