Abstract
We report on a study of meteor trails in the earth’s upper atmosphere, which were imaged with low light level TV cameras simultaneously from two stations, and recorded on video tape at 50 frames/sec. This technique has several advantages over photographic techniques employed previously for recording meteor trails. Firstly the temporal resolution is much better. Secondly, television cameras can detect meteors of apparent magnitude +7 or brighter, whereas photographic cameras can detect only those meteors brighter than magnitude +4. Thirdly, it is much easier to spot faint meteors on the moving video record than on photographic stills. The true position of the trails in space were determined by triangulation against the fixed star background, and hence we could deduce the meteoroid velocities, zenith magnitudes, trail lengths, beginning and end heights of trails, and the heights of maximum brightness of the trails.
