• The EUVE spectrometers have some common background features caused by airglow and scattering in the upper atmosphere. SW- The short-wavelength spectrometer can have a bright rim at shortest wavelengths (left) caused by scattered Lyman alpha. MW- The medium-wavelength spectrometer has a broad feature at 304 Angstroms from geocoronal helium. LW- The long-wavelength spectrometer has a broad feature at 584 Angstroms from geocoronal helium, which includes the 304 Angstrom line in second order.
