Resumen
Para buscar pequeños aumentos de rayos cósmicos asociados con el desarrollo de erupciones solares, se analizaron datos de dos monitores de neutrones ubicados en el hemisferio sur. Se seleccionaron erupciones solares de magnitud 2 o mayor y se realizó el análisis para que los detectores estuvieran ubicados dentro de las zonas de impacto matutino. El comportamiento de la intensidad nucleónica, corregida por la variación diaria superpuesta, no mostró un incremento significativo sobre la «hora cero». Este resultado contrasta con el de Firor, pero concuerda con el artículo más reciente de Towivk y Lockwood. Sin embargo, en el presente trabajo y para una estación, aparece un pico significativo si se aplica otro tipo de corrección. Además, otro aumento significativo surge varias horas después del inicio de las erupciones solares, alcanzando su punto máximo cerca del momento del máximo en la variación media diaria. Los datos examinados se extrajeron de los registros de la Universidad de Tasmania en Mount Wellington (Hobart, Tasmania) y Mawson (Antárctica). El período investigado abarca desde julio de 1957 hasta agosto de 1958.
In order to look for small cosmic ray increases associated with tlie development of solar flares, data from two neutron monitors located in tlie Southern Hemisphere were analvsed. Solar flares of magnitude 2 or greater were selected, and the analysis was carried out for the detectors being located witliin the morning impact zones. The behiaviour of nucleonic intensity, corrected for superposed daily variation, did not show any significative increase over the «zero hour». This result contrasts with that of Firor , but agrees with the more recent paper by Towivk and Lockwood . However, in the present work and for one station, there appears a significative peak if another type of correction is applied. Furthermore, another significative increase arises several hours after the onset of solar flares, closely peaked around the time of máximum in the mean daily variation. Data examined were extracted from records of the University of Tasmania at Mount Wellington (Hobart, Tasmania) and Mawson (Antárctica). The period investigated covers from July 1957 to August 1958.
