[serious] Filmed 05MAY UK, was filming the flashing stars then this flew over

So I star gaze a lot, have done for a decade and the last week I’ve seen a lot strange things I haven’t seen before.

What flys over at the end of the video was originally next to the chimney to the east (chimneys at the start of the video) then it disappeared, k shifted my camera to the flashing stars, then it flew right over.

Phone camera didn’t pick it up great but it flashed green, red, blue and yellow. Much lower than a plane and silent.

Time: 03:50
