Research Abstract

In the JEM-EUSO mission, faint fluorescence induced in the atmosphere by highest energy cosmic rays will be detected with a telescope attached to the International Space Station. In order to examine whether those cosmic rays can be detected even above clouds, balloon-borne experiment was planed to observe nightglow and its reflected and scattered light. Any chance of the balloon experiment was not available in the research period. Instead, nightglow spectrum in 300-400nm was observed at the top of Mt.Norikura. Portions of light from upper atmospheric layers and man-made light were estimated.
