(1996). Latitude variations in interplanetary Lyman-a data from the Galileo EUVS modeled with solar He 1083 nm images. Geophysical Research Letters 23: doi: 10.1029/96GL01978. issn: 0094-8276.

Observations of interplanetary Lyman-&agr; obtained by the Galileo Extreme Ultraviolet Spectrometer (EUVS) experiment near solar maximum in 1990 show a distinct migration in the upwind brightness maximum from 36¿5 ¿N to 6¿5 ¿N ecliptic latitude over a period of several months. Our earlier models based on solar Lyman-&agr; flux proxies appropriate for use in the ecliptic plane (Pryor et al., 1992; Ajello et al., 1994) capture the solar rotation effects present in the data, but do not reproduce this latitude migration. We introduce a new type of model that uses He 1083 nm images to produce a proxy for Lyman-&agr; as a function of both solar longitude and latitude. This model reproduces the observed latitude migration of the Lyman-&agr; brightness maximum. ¿ American Geophysical Union 1996
