NUV/Blue spectral observations of sprites in the 320-460 nm region: ${\mathrm{N}}_2$ (2PG) Emissions

M. J. Heavner, J. S. Morrill, C. Siefring +4

A near-ultraviolet (NUV) spectrograph (320-460 nm) was flown on the EXL98 aircraft sprite observation campaign during July 1998. In this wavelength range video rate (60 fields/sec)…
