Magnetic effects during the solar eclipse of July 11, 1991
Contenido principal del artículo
Resumen
Durante el eclipse total de Sol del 11 de julio de 1991 se realizaron observaciones magnéticas en tres estaciones en México. Los resultados muestran la presencia de un efecto magnético claro del eclipse, tanto en la componente horizontal H, como en la intensidad total F. La declinación D y la componente vertical Z muestran un pequeño efecto, mientras que la inclinación no muestra nada. Las observaciones de F en las tres estaciones son muy similares. El efecto del eclipse es parecido a los cambios en FoE y N(h) reportados varias veces en la literatura, por lo que se sugiere la existencia de una posible relación lineal entre los efectos ionosféricos y magnéticos. Se propone que en próximos eclipses se realicen observaciones simultáneas de fuentes de Rayos-X en el Sol, parámetros ionosféricos y campo magnético superficial para determinar más claramente estas relaciones. Se debe realizar además una revisión a fondo de los modelos teóricos existentes a fin de poder explicar las observaciones.
