【Satellite】	YOTSUBA-KULOVER [Size: 2U]
【Organizations】	Kyushu Institute of Technology
【Service Provider】	Space BD Inc.
【Mission】	Observation of geomagnetic micro-variations to estimate the three-dimensional current systems and their structures during geomagnetic storms and auroral substorms. Imaging of auroras using compact cameras, with analysis of temporal variations in brightness and morphological structures. Investigation of the correspondence between magnetospheric currents and auroral emissions through comparative analysis of magnetic field data and auroral imagery. Research and development of a low-magnetic deployable mechanism aimed at suppressing magnetic interference for high-precision satellite-based magnetic field observations.
