居住在两极附近地区的人们所看到的极光犹如一张五彩缤纷的巨大光幕。
People who live near polar regions see the auroras as giant curtains of shimmering light in a variety of colors.
虽然极光一般仅在两极附近可见，不过在强烈的磁暴对地球磁场的影响下，极光也会在赤道附近出现。
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.
