AB: It has been suggested by Gadsden [1967] that the radiance of Helium 10830 Å line can be used to monitor the solar irradiance in the EUV. Conversely, we can use the 10830 Å line to study the response of the upper atmosphere over the course of a solar cycle. In this paper we will examine Helium emission line at 10830 Å to study the correlation between brightness of the emission line with F10.7 solar flux. The Helium data was acquired from Michelson Interferometers located at two stations, South Pole Station (90° S), Antarctica and Resolute Bay (74.68° N, 94.90° W), Canada. The data will be examined to isolate periods with no auroral contamination. Long term HeI data, from 1992 to 2005, will be presented to study correlation between Helium brightness and the F10.7 solar flux.
