New systems developed in this experiment, such as a natural energy power supply system and an iridium satellite telecommunications system for long-duration automatic observation, can be applied to systems for information exchange in less developed areas lacking adequate social infrastructure.

Observation of high-energy cosmic-ray electronsStudy of source mechanism in deep space

High-energy cosmic-ray electrons with energy of 1 TeV coming from supernova remnants or pulsars were successfully observed for the first time. About 100 events were observed at altitudes above 35 km for 13 days.

Observation of auroral phenomenaAuroral X-ray and electro-magnetic fi eld in the stratosphere

Synthetic observations of auroral phenomena using five instruments (auroral X-ray, VLF wave, electric field, magnetic field, and ionospheric electron density) were carried out by two stratospheric balloons floating closely together. Temporal variations in auroral X-ray images were observed for the fi rst time.
