本文的目的是指出：1）在地磁反转和漂移期间，极光频繁发生的区域将位于与现在截然不同的地理位置; 2）最近提出的两次漂移，Laschamp-Gothenburg事件和Mungo湖事件，都是在旧石器时代晚期（约2000年）。分别为距今12，000年和距今30，000年（诺埃尔和塔林，1975年;莫尔纳和兰瑟，1975年;巴贝蒂和麦克尔欣尼，1972年;弗里德和希利，1974年），并可能为石器时代的主要人群产生频繁的极光显示。第二点可能很重要，因为它打开了一种可能性，即这个时期的一些以前未解释的人工制品和绘画可能是极光形式的代表。
The purpose of this note is to point out: 1) that during geomagnetic reversals and excursion, the zones of frequent auroral occurrence will be located at very different geographical positions than at present; and 2) that two of the most recent excursions that have been suggested, the Laschamp-Gothenburg and the Lake Mungo events, are dated in upper paleolithic period (ca. 12, 000yr BP and 30, 000yr BP respectively (NOEL and TARLING, 1975; MORNER and LANSER, 1975; BARBETTI and MCELHINNY, 1972; FREED and HEALY, 1974)), and could have produced frequent auroral displays to major populations of stone age people. The second point might be important because it opens the possibility that some of the previously uninterpreted artifacts and drawings from this period could be representations of auroral forms.
