BackForwardInstrument:  FUV/WIC 

Instrument details
Acronym FUV/WIC
Full name Far Ultraviolet Imager / Wideband Imaging Camera
Purpose To image the whole Earth and the auroral oval from satellite distances greater than 4 Earth radii to the center of the Earth
Short description Curved image intensifier optically coupled to a CCD to provides a FOV of 17º x 17º. Spectral range: 140-160 nm; temporal resolution 120 s
Background Associated to FUV / SI (Spectrographic Imager) and FUV / GEO (Geocorona Photometer)
Scanning Technique The field of view of 17º x 17º. is imaged by 256 x 256 pixels
Resolution 0.07º, corresponding to a spatial resolutions of < 70 km at apogee distances;
Coverage / Cycle Full magnetospheric view at 2-min intervals
