【正文】 f the date and time of any solar eclipse are known, it is possible to predict other eclipses using eclipse cycles. Two such cycles are the saros and the inex. The saros is probably the best known and one of the most accurate eclipse cycles. The inex cycle is itself a poor cycle, but it is very convenient in the classification of eclipse cycles. After a saros finishes, a new saros series begins one inex later, hence its name: inex. A saros lasts 6, days (a little over 18 years), which means that after this period a practically identical eclipse will occur. The most notable difference will be a shift of 120176。太陽磁場會導(dǎo)致很多影響，稱為太陽活動，包括在太陽表面的太陽黑子、太陽耀斑、和攜帶著物質(zhì)穿越太陽系且不斷變化的太陽風(fēng) [63]。太陽是磁力活躍的恒星，它支撐一個強(qiáng)大、年復(fù)一年在變化的磁場，并且大約每 11年環(huán)繞著太陽極大期反轉(zhuǎn)它的方向 [62]。 in longitude (due to the days) and a little in latitude.
