                         observations, a 30 Mhz riometer, with a Yagi-Uda antenna, was 
                         installed in the vicinities of Sao Bento Alto (28 degrees 
                         42'34{"}S, 49 degrees 30'37{"}W), very near the center of the Moon 
                         shadow. At the same time two other riometer stations were in 
                         operation, one at a lower latitude (C.Paulista) and the other at a 
                         subauroral latitude (brazilian station) in Antarctica. In S.B. 
                         Alto, contrary to the expectations, a noticeable enhancement of 
                         ionospheric absorption started several minutes after the first 
                         contact, lasting for few hours. No such effect was noticed on the 
                         other riometer stations. However, peculiar periodic kinks have 
                         been recorded during and after the solar eclipse by the C. 
                         Paulista riometer. Based on these experimental results a 
                         preliminary interpretaton, based on energetic particle 
                         precipitation from the Van Allen radiation belts, into the
