             abstract = "Balloon-borne X ray measurements with high time resolution were 
                         carried out in the South Atlantic magnetic anomaly to investigate 
                         the fine structure of the precipitation in this region. 
                         Measurements were obtained on two balloon flights launched from 
                         Cachoeira Paulista, Sao Paulo, Brazil, on January 26 and February 
                         1, 1994, and were supported by onboard electric field and 
                         geomagnetic field ground data. In one flight, we have found that 
                         rapid changes do occur in times of about 0.05 s during periods of 
                         a few seconds. They should be considered as the first evidence of 
                         the presence of microbursts in the low L value region of the South 
                         Atlantic anomaly. These microbursts were not correlated with 
                         sferic signatures in the same hemisphere and may be correlated 
                         with magnetic fluctuations in the geomagnetic field. Energy-time 
                         features of the microbursts are examined in order to identify 
                         possible responsible mechanisms.",
