When i direct my camera toward the zenith (almost the same direction where i videotaped ufo flash in september), i recorded two light trails though it might have been actually one due to its high speed that my camera could not catch up with. the lower trail shows the typical blur that can be seen when high-speed object is recorded. about an hour before, i also recorded one light trail at the high in the sky (to the south). slow-motion replay is a half speed. the seacoast is pitch dark with no light. of course i did not record it through the window. time: 5:48 a.M. (and 4:24 a.M.) on december 25, 2019 video camera: sony hdr-cx390
