Measurement Definition: A highly sensitive camera that collects photons radiated by auroral processes.

Instrument	Status/ Accuracy	Instrument Description	Measurement Technology	Timeline
FAI	Operational	Measures the large-scale auroral emissions in the 630-1100 nm wavelength range. The FAI imager system produces 16-bit digital images of the near infrared band at one image per second (CASSIOPE is a 3-axis stabilized platform),and the 630-nm wavelength at two images per minute, giving adequate temporal resolution to investigate the above scientific objectives.	n/a
SSUSI	Operational	Monitors the composition and structure of the upper atmosphere and ionosphere, as well as auroral energetic particle inputs, with spectrographic imaging and photometry.	n/a
WAI	Operational	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.	n/a
