 note = {The X-ray astronomy satellite Ginga detected radiation of artificial origin with the Gamma-ray Burst Detector (GBD). The transient events of non-cosmic origin appeared in February 1987 when the GBD observations started, and disappeared in June 1988. The typical event consists of the two successive bursts separated by a few min. The burst pair has approximate reflection symmetry; the first burst has a slow rise and a rapid decay, the second has a rapid rise and a slow decay. The geographical distribution of the events and their spectra revealed that they were due to geomagnetically trapped electrons., 資料番号: SA0033446000},
