Space Weather Suite / Wide-field Auroral Imager
Observation of Aurora
UV imaging fluxmeter for the range 140-180 nm. Sensitivity ≥6 counts.s-1.Rayleigh-1. The aurora intensity and form reflect the geomagnetic activity, dynamic feature of high-energy particles in the polar region, and coupling of solar wind with ionosphere
Part of the SWS (Space Weather Suite) package
