The milky way is crossing the sky of Ittenhausen, Swabian Jura in southern Germany, at July 22nd to 23rd, 2023. In addition, some moving green ripples of airglow appear in the second half of the night. A thunderstorm far in the south east might have induced gravity waves high in the atmosphere producing the ripples.
