Oneliner	Observe the small perturbation of the geomagnetic field at the LEO.
Description	Observe the small perturbation of the geomagnetic field at the LEO. Measure the global distribution of the Sq (Solar quiet) currents in the dayside ionosphere as well as the disturbed magnetic field variations (such as 3D-structure of the substorm current wedge and Pc5 pulsations) associated with Storm/Substorms. Missions: Magnetic field observation. Aurora observation by optical camera. Charging observation in LEO. Boom deployment mechanism to improve magnetometer observation accuracy. 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.
