摘要

从 1893 年到 1905 年，Ógyalla 磁性观测站每天记录三次地磁场值。我们在介绍这些独特记录的同时，还分析了这一时期三次值得注意的磁暴，即 1894 年 3 月 30 日、1898 年 9 月 9 日和 1903 年 10 月 31 日的磁暴。在这些事件中，除了剧烈的磁场变化外，中欧还观测到了显著的极光。所分析的事件表明，最强烈、最具潜在危险的地磁扰动的来源可能是极光椭圆的电流或与极光椭圆相连的场对准电流。

Regular observations of the geomagnetic field at the Ógyalla observatory (present-day Hurbanovo) near the turn of the 20th century, including magnetic storms accompanied by auroras in March 1894, September 1898, and October 1903

From 1893 to 1905, the values of the geomagnetic field recorded three times a day are available from the Ógyalla magnetic observatory. We introduce these unique records, and at the same time, we provide an analysis of three noteworthy magnetic storms from this period, namely the events on 30 March 1894, 9 September 1898, and 31 October 1903. In addition to violent magnetic variations, remarkable auroras were observed in Central Europe during these events. The analysed events indicate that the source of the most intense, potentially dangerous geomagnetic disturbances can be the electric currents of the auroral oval or the field-aligned currents connected to the auroral oval.
