  • Phase variabilty of Sq (H) and the ionospheric equatorial anomaly 
    Sastri, J. H (The Council of Scientific and Industrial Research, 1982-04)
    A study is made of the behaviour of the equatorial ionization anomaly m the Indian region on days with an abnormal S/subq (H) phase limited to the electrojet belt. The anomaly is found to disappear or reduce in strength quite ...
