在2003年10月29日至31日期间，利用goesseries航天器的磁场数据和llseries航天器的等离子体数据确定了地球同步磁层顶交叉点（GMC）。结果表明，在太阳风等离子体的高速度和密度以及行星际磁场（IMF） bz分量的高负值的高压作用下，大部分时间日侧磁层的大小都大大减小。在长达数十小时的时间里，亚太阳磁层顶在地球同步轨道深处。在主阶段和强磁暴发生的高峰期，日侧磁层表现出强烈的黎明-黄昏不对称性，因此其在午后扇区的大小大大超过了午前扇区的大小。2003年10月30日和31日上午的地磁扰动伴随着周期为5 ~ 10 min、振幅高达0.8RE的全球磁层脉动。
During the period October 29–31, 2003, geosynchronous magnetopause crossings (GMC) have been identified based on the magnetic data of theGOESseries spacecraft and plasma data of theLANLseries spacecraft. It is shown that most of the time the size of the dayside magnetosphere was highly decreased under the effect of very high pressure associated with high velocities and densities of the solar wind plasma, as well as high negative values of theBzcomponent of the interplanetary magnetic field (IMF). For tens of hours the subsolar magnetopause was deep inside the geosynchronous orbit. During the main phase and at the maximum of the strong geomagnetic storms that occurred in the period under consideration, the dayside magnetosphere was characterized by a strong dawn-dusk asymmetry, so that its size in the postnoon sector considerably exceeded the size in the pre-noon sector. The geomagnetic disturbances in the morning on October 30 and 31, 2003 were accompanied by global magnetospheric pulsations with periods of 5–10 min and high amplitude (up to 0.8RE).
