Triangulation of Sprite Features

We report on the results of coordinated sprite measurements made during the summer 2010 observation campaign in New Mexico. More than 15 sprite events were recorded simultaneously from different locations during the nights of 14 and 15 July 2010. These coordinated measurements allow triangulation of sprite altitudes and determination of the relative position of characteristic sprite features. The measurements were made using low-light level video frame-rate cameras mounted on altitude-azimuth telescope mounts. The observations were made from remote locations in northern and eastern New Mexico and coordinated by the use of GPS location and lightning monitoring at Langmuir Laboratory. We compare and contrast the altitudes of the spatial details of different sprite types and the position of sprites relative to the causative lightning. We also compare these results with prior triangulation measurements conducted in previous campaigns.
