The evaluation of the spacecraft-origin magnetic field noise (B_sub(DCnoise)) at the position of the sensor of Magnetic Field Experiments (MGF) onboard the Arase satellite has been performed. We examined the difference between the observation of the magnetic field with MGF and the Tsyganenko-Sitnov 04 (TS04) model field in DSI coordinates (ΔB sub(DSI)) during the quiet time intervals. ΔB sub(z, DSI) was - 0.7 nT on average, which indicates that the B_sub(DCnoise) in the spin-axis direction is quite small. We conclude that the MGF data are well-calibrated and no large B_sub(DCnoise) is included in the measured magnetic field. Although the difference between the MGF observations and the TS04 model in the X sub(DSI) and Y sub(DSI) directions was a few nT, it may be attributed to the TS04 model field, not an observational error of MGF.
