Strong Ionospheric Absorption at Kerguelen Studied By Means of the Characteristic fmin of the Ionosonde [Sur Les Fortes Absorptions Ionosphériques À Kerguelen Etudiees Au Moyen De La Caractéristique fmin De L'Ionosonde]The ionospheric station at Kerguelen, situated at the border of the auroral zone, 57°S geomagnetic latitude, makes possible observations of the different types of absorption occurring at such latitudes. The characteristic fmin in the ionogrammes is an objective parameter although it does not give a quantitative measure of the absorption. The frequency of occurrence of observed values of the parameter ( E, 3 Mhz, B) makes possible qualitative studies of the absorption and its variations. Proton events were particularly frequent during the year 1960.

La station ionosphérique de Kerguelen située à l'extérieur de la zone aurorale sud à 57° de latitude géomagnétique, permet l'observation des différents types d'absorption qui se manifestent à ces latitudes. La caractéristique fmin des ionogrammes est un paramétre objectif mais "sans nuances". La fréquence d'apparition de ce paramètre à des valeurs repérées (E, 3 Mhz, B) permet d'étudier qualitativement l'absorption et ses variations. Les évènements à protons sont particulièrement nombreux au cours de l'année 1960.
