论文摘要
当使用黑子数（SN）作为活性水平的测量时，即将到来的太阳周期（SC）25被认为是相当低的。最受欢迎的预测是NASA小组于2019年进行的，其中包括基于动力型模型的外推的作品。但是，我们发现，使用不同的观测值来测量SC25开始前几年以及2020年SC25开始之后的极性区域活动水平，SC25的高度可能很高。我们认为的极性区域活性似乎与极性冠状孔（CH）活性有关，并且在SC25之前发现的是SC24之前的显着高于SC24，因此，我们建议SN循环确实可以比SC24期间高得多的SN周期高得多。
The forthcoming solar cycle (SC) 25 was beleived to be rather low when using the sunspot number (SN) as a measurement of the level of activity. The most popular prediction was made by the panel of NASA in 2019, including works based on extrapolations of dynamo-type models. We however discovered that using different observations to measure the level of polar regions activity several years before the start of SC25 and also after the start of the SC25 in 2020, the height of the SC25 could be high. The polar regions activity we considered seems related to the polar coronal holes (CH) activity and it is found significantly higher before the SC25 that it was before the SC24 and accordingly, we suggest that the SN cycle could indeed be much higher than during the SC24 that was a low SN height cycle.
