Back in 2008 solar scientists saw a high-latitude, reversed-polarity sunspot, suggesting the start of a new solar cycle.

在2008年的时候，太阳科学家们观测到一个位于太阳高纬地区反极性的黑子，他们认为这是新一轮太阳活动开始的标志。

It is shown that the TEC variation is associated with the local time the solar perturbing occurred and the coupling of the ionospheric particles of high latitude with the solar particle.

由此看出，磁暴期间电离层tec的变化直接与太阳扰动发生的时间及其对高纬电离层的耦合有关。

But, also like ancient mariners (who knew their latitude, but not their longitude), such solar reckoning cannot tell them when to stop.

During this eruption, the solar particles hitting the atmosphere produced auroras across the whole world, not just at high-latitude locations as is normally the case.
