On latitude dependence of geomagnetic storm after-effects in ionospheric absorption
Abstract 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 single hop A3 transmission paths with ionospheric points at $ Φ_{geomag} $ = 3.54°N and ∼6.40°N (15.40 MHz), $ Φ_{geomag} $ ∼9°N (4.87 MHz), and $ Φ_{geomag} $ ∼11°N (6.09 MHz) respectively. Presently, the results have shown that enhancement in absorption following major storms could be traced to the low latitude of 3.54°N.
