Silver ripples of noctilucent clouds became visible in the twilight of June 21st, 2019, summer solstice. They were covering more than half the sky from central Germany at first sight. Later on, the visible part was receding to the north with the sun being low under the northern horizon. Only the sunlit parts of these extremely high ice clouds are brightly visible.
