We report simultaneous observations of intense fluxes of quasi-trapped energetic electrons and substantial enhancements of ionospheric electron concentration (EC) at low and middle latitudes over Pacific region during geomagnetic storm on 15 December 2006. Electrons with energy of tens of keV were measured at altitude of ~800 to 900 km by POES and DMSP satellites. Experimental data from COSMIC/FS3 satellites and global network of ground-based GPS receivers were used to determine height profiles of EC and vertical total EC, respectively. A good spatial and temporal correlation between the electron fluxes and EC enhancements was found. This fact allows us to suggest that the quasi-trapped energetic electrons can be an important source of ionospheric ionization at middle latitudes during magnetic storms.

Geomagnetically Induced Currents in the Irish Power Network during Geomagnetic Storms
地磁感应电流是地球空间天气的一种常见危害。它们发生在电力传输网络中，已知在高纬度和中纬度国家都有不利影响。在这里，我们研究了五次地磁风暴（2016年3月6日至7日、2015年12月20日至21日、2015年3月17日至18日、2003年10月29日至31日和1989年3月13日至14日）期间爱尔兰输电网络（地磁纬度54.7--58.5 $^{\circ}$ N）中的GIC。本文采用平面波法模拟了大地电场，并建立了大地电磁模型。然后计算了220、275和400 kV输电网络的GIC。在所研究的最大风暴期间，用我们的MT模式计算的峰值电场高达3.8 V km \textsuperscript{-1}，伴随的GIC高达23 A。用均匀电阻率模型计算，其峰值分别为1.46 V km \textsuperscript{-1}和25.8 A.我们发现，三个400和275千伏变电站是最有可能的位置，爱尔兰Transformers经历大GIC。
