                         s{\'o} por causa da falta de observa{\c{c}}{\~o}es nesta faixa

                         e obtivemos evid{\^e}ncia deste fato. O evento do dia 21 de Maio

                         solares. Ele foi observado em diferentes bandas de energia do 
                         espectro e nos deu novas condi{\c{c}}{\~o}es de contorno para o 
                         fen{\^o}meno f{\'{\i}}sico no Sol. O evento do dia 21 
                         necessitou uma an{\'a}lise detalhada dos modelos de 
                         interpreta{\c{c}}{\~a}o atuais e sugeriu a presen{\c{c}}a de 
                         el{\'e}trons relativ{\'{\i}}sticos durante a fase impulsiva. 
                         Neste trabalho n{\'o}s sugerimos o mecanismo Sincrotron/Compton 
                         inverso para explicar a emiss{\~a}o submm/raios X e a curta 
                         dura{\c{c}}{\~a}o dos pulsos. As novas condi{\c{c}}{\~o}es de 
                         contorno para a libera{\c{c}}{\~a}o prim{\'a}ria de energia 
                         favorecem o modelo de Tajima e Sakai, baseado na teoria da 
                         coalesc{\^e}ncia de ilhas magn{\'e}ticas. ABSTRACT: The main 
                         purpose of this work is to analyse the characteristics of peculiar 
                         solar events that could be produced by ultrarelativistic electrons 
                         and try to define the new boundary conditions for the primary 
                         energy release during impulsive phase. It seems that submillimeter 
                         onission in solar fiares is no a rare phenomenum, there is no much 
                         evidence of that, just due the lack of observations in this range 
                         of the spectrum. During May 1984 we observed the Sun at 90 GRz 
                         with high time resolution and high sensitivity, and obtained 
                         evidence of this. The May 21, 1984 event, at 1326 UT is the best 
                         example of the high energy manifestation during solar events. It 
                         was observed in different energy bands of the spectrum and gave us 
                         new boundary conditions for the physical phenomena in the Sun. The 
                         May 21 event required a detailed analysis of the current 
                         interpretation models and suggested the presence of relativistic 
                         electrons during the impulsive phase. In this case we suggested 
                         Syncrotron/Inverse compton mechanism to explain submm/X ray 
                         emissiom and short pulse duration. The new boundary conditions for 
                         primary energy release favored Tajima and Sakai's model, based in 
                         magnetic island coalescence theory.",
