A study of the response of some ionospheric parameters and their relationship in describing the behaviour of ionospheric mechanisms during the solar eclipse of 21 August 2017 is presented. Mid-latitude stations located along the eclipse path and with

HF absorption enhancements following major geomagnetic storms are analysed, using the superposed epoch method, to examine the geomagnetic latitude limit of the after-effect phenomenon. The absorption data were obtained from one double hop and two sin

Earlier investigations of the influence of geomagnetic activity on radio wave absorption were based on storm selection criterion: ΣK P ≥ 30. This criterion lumped together weak, moderate, and strong storms, and favouring weak and moderate storms m

Study and prediction of magnetic storms are becoming increasingly important as they have profound influence on human and societal life. Intense solar flares release very high energy particles that can be as injurious to human as the low energy radiat

A study is made of the moderate geomagnetic storm of July 8, 1975 (Dst min =-60 nT) and its associated ionospheric storm using solar wind parameters and foF2 data obtained from ionosonde stations in East Asian longitudinal sector. The storm was found

An investigation is made of the intense storms of April 12- 14, 1981(Dst =-311nT) in an attempt to contribute to the current understanding of solar wind structures and magnetospheric processes that generate intense magnetic storms, as well as explain

A large foF2 data base was collected for the four magnetic storms occurring in January 10, 1976; April 12-13, 1981; October 29, 1973 and July 8, 1975; for the low latitude station of Manila (14.70N) in the East Asian sector. Also, plots of D(foF2) de

Background: The radial collateral ligament was previously believed to be the only ligament existing at the lateral aspect of the elbow joint until Morrey and An (1976) classified the ligaments to include radial collateral (RCL) and lateral ulnar coll
