Description

An omnidirectional gamma ray detector was flown on a stratospheric balloon on December 15, 1978 from Sao Jose dos Campos, Brazil. After reaching ceiling, an increase in the count rate was observed. After considering the probable sources causing this increase, it is suggested that this increase might be due to the supernova remnant, first observed optically in May 1978 in galaxy MCG-4-32-23. The energy spectrum of supernova shows a flattening of slope above 1.5 MeV. (Author)

Abstract (Portuguese)

Um detetor de raios gama omnidirecional foi icado por um balao estratosferico em 15 de dezembro de 1978, partindo de Sao Jose dos Campos, Brasil. Apos alcancar o teto, observou-se um aumento na taxa de contagem. Apos consideracao de fontes provaveis desse aumento, e sugerido que ele se deva ao remanescente de supernova observado oticamente pela primeira vez em maio de 1978 na galaxia MCG-4-32-23. O espectro de energia da supernova exibe um achatamento da inclinacao acima de 1,5 MeV. (Autor)
