FIELDWORK

Research/Observation Title

Auroral spectrograph

Science Summary (common)

[purpose] Studies on how the auroral and airglow spectra change both spatially and temporally with respect to changes in the upper atmospheric environment. [outline] The auroral spectrograph consists of a large fish-eye lens (180-degree FOV,f = 6mm,F1.4),a slit which passes the light from the sky along meridian direction, a collimating optics,a grism with 600 gr/mm,an imaging optics,and a digital camera with a bare,back-illuminated CCD chip of 512 x 512 pixels. The spectrograph covers a wavelength of 420-740 nm with spectral bandwidth of 0.6 nm, and with spatial resolution of 0.18 x 0.18 degrees. The sensitivity is 0.06 cts/pixel/Rayleigh/sec which enables sampling rate of a few seconds per image. This also contributes to the collaborative study with the EISCAT Svalvard Radar (ESR) and other ground-based observations.
