The Monochromatic Auroral Imager


Polar Research Institute of China (PRIC)

Scientific objectives
The camera is designed to detect all-sky auroral morphology in multiple wavelength bands at extreme low light conditions. A twin instrument is installed at the Chinese Arctic Yellow River Station in Ny-Ålesund.

The distance between Ny-Ålesund and Longyearbyen (~120 km) is ideal for triangulation to determine auroral altitudes and borders.
