The solar can also be on the peak of its 11-year cycle, which implies photo voltaic exercise shall be at an all-time excessive for the subsequent yr or so. When the solar is that this lively, it throws extra photo voltaic flares than regular. Since photo voltaic flares hitting Earth are how auroras are shaped, which means there’s an excellent greater probability of a superb aurora occurring over the subsequent month.
Nonetheless, photo voltaic climate is loads like common climate right here on Earth. It is troublesome to foretell. So, there could also be a quiet aurora season regardless of all the percentages being in favor of an enormous aurora coming quickly.
