本文研究了在具有强磁场的中小强度亚暴期间，磁共轭站H分量负海湾的最大变化对IMF BY分量符号的依赖性。|ΔH|最大值< 750 nT，BZ < 0，|BZ/ BY| < 1已被研究。根据Kotzebue（Φ = 64.5°; Λ = 249.7°）和Macquarie Isl.（Φ = −64.5°; Λ = 247.8°）和西半球的Leirvogur（Φ = 65.3°; Λ = 68.2°）和Syowa（Φ = −66.1°; Λ = 71.0°）站的观测结果表明，在BY < 0时，|ΔH|最大值在南半球较大，在BY > 0时较大，相反，在北方半球较大。
The dependence of maximum variations of H-component negative bays at magnetic conjugate stations on a sign of the IMF BY-component during the substorms of small and moderate intensity with |ΔH|max < 750 nT developed at BZ < 0 and |BZ/ BY| < 1 has been studied. By data from Kotzebue (Φ = 64.5°; Λ = 249.7°) and Macquarie Isl. (Φ = −64.5°; Λ = 247.8°) observatories in the eastern hemisphere and Leirvogur (Φ = 65.3°; Λ = 68.2°) and Syowa (Φ = −66.1°; Λ = 71.0°) stations in the western hemisphere it is shown that at BY < 0 the absolute values of negative bays |ΔH|max are greater in the southern hemisphere and at BY > 0, on the contrary, in the northern hemisphere.
