We investigated the difference between the magnetic field observed by the Arase spacecraft and the Tsyganenko 89 model field (ΔB) during geomagnetic quiet period to determine the DC component of spacecraft-origin magnetic field noise at the position of Magnetic Field Experiment (MGF) onboard the Arase spacecraft. The median value of the Z-component of ΔB in the Despun Sun sector Inertia (DSI) coordinates is very small (-0.6 nT); therefore, MGF has a good magnetic field cleanness and is well-calibrated. We also found that the Z-component of the magnetic field in the SM coordinate system observed by Arase is usually larger than that of the model field by - 3 nT. The difference between time periods for the data used in this study and for the data to create the Tsyganenko 89 model may cause the discrepancy.
