Magneto-Ionic Triple Splitting Over Delhi

摘要

The paper presents some observations of the rare occurrence of triple magneto-ionic splitting over Delhi. The various possible causes for the occurrence of this phenomenon at the low geomagnetic latitude of Delhi have been discussed. It has been indicated that the triple splitting is likely to be caused by the longitudinal propagation of the ordinary ray associated with an increase in the collisional frequency of the ionospheric layers.
