Abstract [en]

We performed 100aEuro-fps stereoscopic imaging of aurora for the first time. Two identical sCMOS cameras equipped with narrow field-of-view lenses (15A degrees by 15A degrees) were directed at magnetic zenith with the north-south base distance of 8.1aEuro-km. Here we show the best example that a rapidly pulsating diffuse patch and a streaming discrete arc were observed at the same time with different parallaxes, and the emission altitudes were estimated as 85-95aEuro-km and > aEuro-100aEuro-km, respectively. The estimated emission altitudes are consistent with those estimated in previous studies, and it is suggested that high-speed stereoscopy is useful to directly measure the emission altitudes of various types of rapidly varying aurora. It is also found that variation of emission altitude is gradual (e.g., 10aEuro-km increase over 5aEuro-s) for pulsating patches and is fast (e.g., 10aEuro-km increase within 0.5aEuro-s) for streaming arcs.
