The Fast Auroral Imager (FAI) consists of two charge-coupled device (CCD) cameras: one to measure the 630 nm emission atomic oxygen in aurora and enhanced night airglow; other observe prompt auroral emissions 650 1100 range. High sensitivity is realized through combination fast lens systems (f/0.8) CCDs high quantum efficiency (>90 % max). cameras have a common 26 degree field-of-view provide nighttime images about km diameter from apogee at 1500 km. near infrared camera provides up 0.1 s exposure per second with spatial resolution few when pointing nadir direction, making it suitable for studies dynamic phenomena. 630-nm has been designed image 0.5 every 30 seconds. Launch satellite occurred on September 29, 2013. Following description instrument, sample are presented.
