On August 14, 1998, 3 separate daytime sprite events were detected via a unique extremely low frequency (ELF) sprite signature. The onset of the sprite ELF signatures was delayed by 11.0--13.2 ms from positive cloud-to-ground strokes which had attained exceptionally large charge moment (charge times height) changes of 3900--6100 C⋅km. It is shown that a charge moment change of 6100 C⋅km may have been sufficient for conventional break-down at ≃54 km altitude, assuming an experimentally measured ion conductivity profile of Holzworth et al., [1985>. The daytime sprites themselves contained unusually large charge moment changes of ≃2800 C⋅km, ≃1200 C⋅km, and ≃910 C⋅km. ¿ 2000 American Geophysical Union |
