Scientific paper

Spectra from individual sprite streamer heads and column-shaped glows were observed with a high-speed slit-less spectrograph at 10,000 fps during an aircraft campaign in August 2009. Blue emissions were recorded from streamer heads in five events and from glows in one event. The streamer heads consistently have a larger fraction of blue emission spectra compared to the glows for the events in 19 August 2009. It confirms, at unprecedented spatial, temporal, and spectral resolution, the more energetic nature of sprite streamer heads than column-shaped glows. For the events on 19 August 2009, estimated local electric fields in the streamer heads are 0.4-0.9Ek, and those in the glows are 0.3-0.6Ek, where Ek is the conventional breakdown threshold field.
