Scientific paper

Rocket measurements have been made of daytime O I and N2(+) emissions at heights of 80-160 km over the Sea of Norway in May 1980. In multitier auroras below 110 km, the 391.4/557.7 emission intensity ratio is 3-8 times greater than that at nighttime; above 150 km, this ratio increases by 8-20 times in auroras with an importance of 2. It is suggested that increases in N2(+) brightness above 160 km may be due to resonant scattering of solar radiation by N2(+) ions in the ground X2Sigma + g state.
