Monitor Data

The super neutron monitor data from Goose Bay and Deep River for 1965 have been analyzed to give month-to-month changes of the first and second harmonics of the solar-diurnal variation. Using these results together with various suppositions about the nature of the cosmic-ray distribution vector, information is obtained concerning the orientation of the interplanetary magnetic field.

Diurnal and semidiurnal variations of the data from the worldwide network of neutron monitors during 1958 are analyzed using the receiving-vector method. It is shown that there exists an "antisymmetric" diurnal variation, i.e., a variation with opposite phases in the northern and southern hemispheres. After correction for the distortion due to the geomagnetic field, it is found that this variation has an amplitude of 0.03% and an hour of maximum at 21.5 hours in the northern hemisphere. If the variation is due to cosmic-ray screening in the interplanetary magnetic field, this field must have a slope of 7° with respect to the solar equatorial plane.

El propósito de este trabajo d revisión es el de resumir y discutir los avances recientes en la investigación hecha en el campo de la propagación de los rayos cósmicos en el medio interplanetario. Se presentan los conceptos actuales acerca del viento solar y la heliosfera. Se analiza el problema es la propagación de partículas en el contexto de los eventos solares y su tratamiento bajo distintos enfoques, llegándose a una comparación de los distintos resultados para los coeficientes de transporte. Se revisa también el problema del transporte en la heliosfera exterior.
