タイトル(掲載誌)宇宙航空研究開発機構研究開発報告 = JAXA Research and Development Report
一般注記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.
