JAXA Research and Development Report: Research reports on high altitude balloons
In order to make the two-dimensional image for auroral X-rays and to obtain the energy spectrum of aurora with energy range from 30 keV to 778 keV, the Polar Patrol Balloons No8 and No10 (PPB#8 and PPB#10) were launched in rapid succession to form a cluster of balloons during their flight on Jan. 13, 2003 from Syowa Station. They drifted westward 0.5 circumpolar rounds over Antarctica, covering 9-12 g/cm2 atmospheric depth and 55.5 deg -66.4 deg geomagnetic latitude. From Jan. 22 to 25, 2003, several auroral events were detected by PPB#8 and PPB#10 at the same time. On Jan. 23, 2003, PPB#10 and PPB#8 observed auroral X-ray events in succession. PPB#8 which was located about 650 km west from PPB#10 observed auroral X-ray event after PPB#10 with delay time 218 sec. It is suggested that the auroral X-ray source region moved from east to west with speed of about 3.0 km/s. In this paper, we present the feature of these concurrently observed auroral X-ray events.
