ID-412 : Auroral spectrograph
Type
FIELDWORK
Research/Observation Title
Auroral spectrograph
Science Summary (common)
A new aurora spectrograph is installed in Longyearbyen to study how the auroral and airglow spectrum changes both spatially and temporally with respect to changes in the upper atmospheric environment. It consists of a large fish-eye lens (180 degree FOV, F=6mm, F 1.4), a slit which passes the light from the sky along meridian direction,a collimating optics, a grism with 600gr/nm, 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 420-740nm with spectral bandwidth of 0.6nm, and with spatial resolution of 0.18 x 0.18 degrees. The sensitivity is 0.06cts/pixel/Rayleigh/sec which enables sampling rate of a few seconds per image. This also contributes to the collaborative study with the EISCAT Svalbard Radar (ESR) and other ground-based observations.
