The mission of Advanced Ionospheric Probe (AIP) onboard FORMOSAT-5 (F5) satellite is to detect pre-earthquake ionospheric anomalies (PEIAs) and observe ionospheric space weather. F5/AIP plasma quantities in the nighttime of 22:30 LT (local time) and the total electron content (TEC) of the global ionosphere map (GIM) are used to study PEIAs of an M7.3 earthquake in the Iran–Iraq border area on 12 November 2017, as well as signatures of two magnetic storms on 7 and 21–22 November 2017. Statistical analyses of the median base and one sample test are employed to find the characteristics of temporal PEIAs in GIM TEC over the Iran–Iraq area. The anomalous increases of the GIM TEC and F5/AIP ion density over the epicenter area on 3–4 November (day 9–8 before the M7.3 earthquake) agree with the temporal PEIA characteristics that the significant TEC increase frequently appears on day 14–6 before 53 M ≥ 5.5 earthquakes in the area during 1999–2016. The spatial analyses together with odds studies show that the PEIAs frequently appear specifically over the epicenter day 9–8 before the M7.3 earthquake and day 10–9 before a M6.1 earthquake on 1 December, while proponent TEC increases occur at worldwide high latitudes on the two magnetic storm days. The F5/AIP ion velocity uncovers that the PEIAs of the two earthquakes are caused by associated eastward electric fields, and the two positive storm signatures are due to the prompt penetration electric fields.

福星五号（F5）卫星搭载的先进电离层探测器（AIP）的任务是探测震前电离层异常（PEIA）并观测电离层空间天气。使用 LT（当地时间）夜间 22:30 夜间的 F5/AIP 等离子体数量和全球电离层图 (GIM) 的总电子含量 (TEC) 来研究伊朗-伊拉克边境 M7.3 地震的 PEIA 2017年11月12日的磁暴特征，以及2017年11月7日和2017年11月21日至22日的两次磁暴特征。采用中值基数统计分析和一次样本检验来发现伊朗-伊拉克上空GIM TEC的时间PEIA特征区域。 11月3日至4日（M7.3地震前第9天至第8天）震中区GIM TEC和F5/AIP离子密度的异常增加与PEIA的时间特征一致，即TEC显着增加经常出现在第14天–6 在 1999 年至 2016 年期间该地区发生 53 M ≥ 5.5 级地震之前。空间分析和几率研究表明，PEIA 经常出现在 M7.3 地震前的第 9-8 天和 12 月 1 日 M6.1 地震前的第 10-9 天，而支持者 TEC 的增加发生在全球最高水平。两个磁暴日的纬度。 F5/AIP离子速度揭示了两次地震的PEIA是由相关的东向电场引起的，两次正的风暴特征是由于瞬发电场引起的。
