In this article the behavior over time of the Earth’s magnetic field in the municipality of Fúquene, Colombia is determined. From the historical series of magnetic field measurements over the Earth’s surface provided by the Fúquene geomagnetic observatory, which contains the historical record of 60 years of hourly measurements of the terrestrial magnetic field components, a regression analysis of the terrestrial magnetic field components as a function of time was performed. Two methods were used to remove outliers that complemented each other, the Z_score method and the Hampel filter. In the analized period since 1955 to 2015, the intensity of the terrestrial magnetic field has decreased by 14%, with a projected variation of more than 25% for the year 2055. The magnetic field intensity change rate 0.08675 [μT/year] was calculated and compared with the information reported by NOAA (National Oceanica and Atmospheric Administration) finding an excellent agreement. Besides, the ocurrence of geomagnetic storms in the data was determined, from the gradients of the horizontal component of the magnetic field during the main solar events that occurred in the study period. According to the historical behavior of the terrestrial magnetic field components, in the future we expect that the decreasing of Earth’s magnetic Field continues, which would imply a higher threat to the effects of space weather in the country, such as the generation of GICs (Geomagnetically Induced Currents) in the Colombian electricity system.

En este artículo se determina el comportamiento en el tiempo del campo magnético terrestre en el municipio de Fúquene, Colombia. A partir de la serie histórica de mediciones de campo magnético sobre la superficie de la tierra, proporcionada por el observatorio geomagnético de Fúquene, que contiene el registro histórico de 60 años de mediciones por hora de las componentes del campo magnético terrestre, se realizó un análisis de regresión de las componentes del campo magnético terrestre en función del tiempo. Se utilizaron dos métodos para eliminar los valores atípicos que se complementaban entre sí, el método Z_score y el filtro Hampel. En el período analizado desde 1955 hasta 2015, la intensidad del campo magnético terrestre ha disminuido en un 14 %, con una variación proyectada de más del 25 % para el año 2055. Se calculó la tasa de cambio de intensidad del campo magnético 0.08675 [μT/año] y se comparó con la información reportada por NOAA (Administración Nacional Oceánica y Atmosférica) encontrando una excelente concordancia. Además, se determinó la ocurrencia de tormentas geomagnéticas en los datos, a partir de los gradientes de la componente horizontal del campo magnético durante los principales eventos solares ocurridos en el período de estudio. Según el comportamiento histórico de las componentes del campo magnético terrestre, en el futuro esperamos que continúe la disminución del Campo magnético terrestre, lo que implica una mayor amenaza a los efectos del clima espacial en el país, como la generación de GICs (Corrientes Inducidas Geomagnéticamente) en el sistema eléctrico colombiano.
