Report of Japan-Norway balloon campaign at Andoya and Stamsund, 1982

Abstract

This report describes a result of the Japanese balloon campaign carried out in March 1982,at Stamsund (68°09′N, 13°46′E) in northern Norway. The objective of this campaign was to study auroral particle precipitation and related ionospheric phenomena. Two balloons were successfully launched on March 19 and 20,1982. The first one was launched in the recovery phase of an auroral substorm, and X-ray pulsation and microburst, correlated well with VLF emissions, were observed. The second one was launched at the substorm time, and the change of the ionospheric electric field direction was observed in association with auroral activities. The process of planning, the preparation and the operation for this campaign are also described for the convenience of future balloon campaign.
