Due to the magnetic effects, the occurrence rate of the instability is not symmetric in longitudes even at the magneticequator.
由于地磁位型的不同，发生率的分布并不具有经度对称性，即使在磁赤道附近也如此。

When the magnetic field is at its strongest, and sunspots at their most plentiful, they cluster close to the equator.
当磁场最强，太阳黑子最丰富的时候，它们会聚集在赤道附近。

While aurora are generally only visible close to the poles, severe magnetic storms impacting the Earth’s magnetic field can shift them towards the equator.
