The observation of lightning from space can have several advantages, including views of the tops of clouds, that can facilitate the study of in-cloud lightning as well as the world-wide access provided by the orbital parameters of a satellite. Given

We have identified for the first time an energy-time dispersion of precipitating electron flux in a pulsating aurora patch, ranging from 6.7 keV to 580 keV, through simultaneous in-situ observations of sub-relativistic electrons of microburst precipi
