Resumen
Se analiza la variación de la intensidad de los rayos cósmicos durante tres tormentas magnéticas de julio de 1959. Se utilizaron datos de monitores de neutrones en Mina Aguilar (4 000 m s.n.m. t 12° S latitud geomagnética), Buenos Aires (0 m s.n.m., 23° S) y Ellsworth (0 m s.n. m., 67° S). Se describe un método que da información detallada sobre la variación del espectro de rayos cósmicos primarios durante las tormentas magnéticas. Este método se aplica al presente caso, dando los siguientes resultados: la forma del espectro de variación primaria responsable de las tres tormentas de julio fue aproximadamente la misma que la de la tormenta de mayo de 1959. Durante la recuperación de la segunda tormenta se detectó una inyección de partículas de baja energía de considerable intensidad. Se determina la dependencia temporal de este flujo extra. Durante la recuperación lenta después de la última tormenta, el espectro de variación primaria cambia su forma de manera similar a la recuperación de la tormenta de mayo. Se muestra la correlación de estos efectos con la actividad geomagnética.
The cosmic ray intensity variation during three magnetic storms of .July 1959 is analyzed. Data from neutron monitors at Mina Aguilar (4 000 m o.s.l. t 12° S geomagnetic latitude), Buenos Aires (0 m o.s.l., 23° S) and Ellsworth (0 m o.s.l., 67° S) were used. A method is described wliich gives detailed in forimation on the variation of the primary cosmic ray spectrum during magnetic storms. This method is applied to the present case, giving tlie following results: the shape of the primary variation spectrum responsible for the three July storms was approximately the same as that of the May 1959 storm. During the recovery of the second storm , an injection of considerable intensity of low energy particles was found. The time dependence of this extra flux is determined. During the slow recovery after the last storm , the primary variation spectrum changes its shape in a similar way as in the May storm recovery. The correlation of these effects with geomagnetic activity is shown.
