很少有研究收集和分析阿拉伯文献中记录的天文事件。在本文中，我们提出了一些额外的事件报告在四个阿拉伯历史来源，可以归类为极光。这些观测发生在9世纪至20世纪，覆盖了大片地理区域：北非、阿拉伯半岛和中东。其中一些极光是在地磁纬度非常低的地方观测到的，例如公元1919年在也门观测到的极光，可以被认为是阿拉伯学者有史以来记录的纬度最低的极光之一。在同一份也门资料中，作者描述了1883年10月3日至11月1日的黄昏现象，这可以被认为是1883年8月26日至27日喀拉喀托大爆发引起的大气光学现象。我们还注意到，其中一个持续7天的事件可能与1870年9月24日至25日极光的长期表现相吻合。包括已发表的记录，我们编制了一个迄今为止最完整的阿拉伯语来源的潜在极光候选者目录。该数据集可用于研究历史上的太阳活动变化和磁暴。1872年2月4日，在麦加（MLAT）看到了一个有趣的极光。这一事件进一步证明了极光向赤道方向的延伸，以及1872年大磁暴对行星的影响。最后，应该强调的是，在蒙德极小期（MM）期间没有极光观测记录。
Few studies have collected and analyzed the astronomical events recorded in Arabic literature. In this paper, we present some additional events reported in four Arabic historical sources that could be classified as an aurora. These observations occurred from 9th to 20th century and cover a large geographic area: North Africa, Arabian-Peninsula and Middle-East. Some of them were observed at very low geomagnetic latitude, such as the event seen in Yemen in AD 1919 that can be considered as one of the lowest latitude auroras ever documented by Arabic scholars. In the same Yemenite source, the author describes a twilight phenomenon of 1883 October 03–November 01 which can be considered as an atmospheric-optical phenomenon arising from the major explosive eruptions of Krakatoa in 1883 August 26–27. We also noticed that one of the events which was seen for 7 days coincide probably with the prolonged manifestation of auroras of 1870 September 24–25. Including published records, we compiled a so far most complete catalog of potential auroral candidates in the Arabic sources. This data set can be used in order to study the solar activity variations and magnetic storms in the historical past. One of the interesting auroras was seen in Mecca ( ∼ 17 ∘ $sim17^{circ}$ MLAT) in 1872 February 04. This event is further evidence for the equatorward extension of auroral display and the planetary consequences of the great geomagnetic storm of 1872. Finally, it should be underlined that no aurora observations were recorded during the Maunder minimum (MM).
