  • Characteristics of night sporadic-E at Kodaikanal 
    Sastri, J. H; Murthy, B. S (National Institute of Science Communication And Information Resources, 1975-09)
    Published ionospheric data were used as a basis to study the characteristics of nighttime Es (blanketing frequency, virtual height, and transparency range) at Kodaikanal (geomag. lat.: 0.6 N; dip: 3.5 N) with the object ...
  • Forenoon bite-out in f0F2 at low latitudes 
    Sastri, J. H; Ramesh, K. B (The Council of Scientific and Industrial Research, 1982-04)
    Evidence is presented showing that the longitudinal extent of the forenoon bite-out in f0F2 at low geomagnetic latitudes can sometimes be very narrow and that marked differences in the extent of the development of the ...
  • Ionospheric electron content and equivalent slab thickness in the equatorial region 
    Das Gupta, A; Basu, S; Bhar, J. N; Bhattacharyya, J. C (American Geophysical Union, 1975-02)
    The ionospheric total electron content and equivalent slab thickness in the equatorial region around 75° E have been studied. It is found that the slab thickness exhibits a strong latitudinal dependence with a maximum at ...
  • Ionospheric total electron content and slab-thickness at low latitudes in Indian zone 
    Rastogi, R. G; Iyer, K. N; Sharma, R. P (Indian Academy of Sciences, 1977-06)
    Observations of Faraday rotation of beacon signals from low orbiting satellite BE-B recorded at one station near the dip equator (Kodaikanal, dip 3·4° N) and at another station near the peak of the equatorial anomaly ...
  • On the characteristics of the SC of 13 July 1961 in the Indian equatorial region 
    Sastri, J. H (Japan Science and Technology Agency, 1975-07)
  • On the occurrence of AQDs at Kodaikanal 
    Sastri, J. H; Murthy, B. S (The Council of Scientific and Industrial Research, 1978-02)
    A study is made of the occurrence of 'abnormal quiet days' (AQDs) at Kodaikanal (10 deg 14 min N, 77 deg 28 min E; dip 3.5 deg N) using H-field data over a 26-yr period (1950-1975). The results show distinctive differences ...
