Mean latitude of Félix Aguilar Observatory: study of its variation

Abstract

The values of the latitude for each tenth of year are deduced from the curve which represents the variation of the instantaneous latitudes, as a result of systematic observations carried out during 15 consecutive yares with the Danjon Astrolabe belonging to "Félix Aguilar Observatory" of San Juan State University (Universidad Nacional de San Juan). With these values, a series of mean values, also for each tenth of a year, are calculated using the Orlov formula. Thus, the necessary data for the curve which represents the variation of the mean latitude are obtained. These results are analyzed.
