 note = {P(論文), This report presents the spatial distributions of auroral X-rays obtained by the balloon flight named AZCO-C1,which was launched from Norway in July 1985. A time sequence of auroral X-ray images were derived by using a set of three NaI (T1) scintillation counters for each of the three different energy channels : 22-35,35-55 and 55-88keV. The precipitation region of energetic particles and its modulations with time were well demonstrated, though the X-ray enhancements were only three times the background flux.},
