About this image

This event was caught on 4K video on Geminid maximum night. This is a crop of the original video downsampled by a factor of 2. The original full resolution full sized and cropped videos are here and here. This GIF consists of 110 frames taken from the original 25fps video (i.e. around 4.5s duration). The FoV is 15 x 5 deg and the original video has a resolution of 23.2 arcsec/pixel which is approximately 15m/pixel on the plane-of-sky at a distance of 130km. The video shows the bright, ablating meteoroid as a streak due to the 1/25s shutter speed leaving behind an ionised train which is quickly distorted by high-altitude winds.
