In for the long run ...
The Upper Atmospheric Physics Division of the Polar Research Institute of China (PRIC) will install a state of the art auroral imager at KHO. The initial contract is for a period of 5 years starting autumn 2011.
The cooperation will kick off in August with sensitivity certification of 3 camera systems at the calibration facilities at UNIS, including instruments operated at the Arctic Yellow River Station in Ny-Ålesund.
The cameras are designed to detect all-sky auroral morphology in multiple wavelength bands at extreme low light conditions. The distance between Ny-Ålesund and Longyearbyen (~120 km) is ideal for triangulation to determine auroral altitudes and borders.
Instrument specifications:
Manufacturer: Keo Scientific Ltd.
Name: Monochromatic Auroral Imager
Front Lens: Mamiya 645 24 mm/F4.0
Spatial coverage: All sky view - FOV 180 deg.
Detector: EMCCD Andor iXon+ (E2V CCD 201, 1024×1024 pixels)
Time resolution: msecs; Cooling: -80 deg.; 14-16 bits resolution
Filter wheel (6 x 4 inch diameter apertures - temperature stabilized)
Center wavelengths:
[CH1] 427.8 nm, [CH2] 432.0 nm, [CH3] 540.0 nm,
[CH4] 557.7 nm, [CH5] 620.0 nm, [CH6] 630.0 nm.
