Abstract
Ionospheric effects of the total solar eclipse of 24 October 1995 over Ahmedabad, with maximum obscuration of 83 % at 0800 hr (75° EMT), are studied based on radio soundings using KEL (KEL Aerospace Pvt. Ltd.) digital ionosonde. Comparison with the data recorded on control day, 23 October 1995, shows reduction of 35 %, 45 % and 28 % in the critical frequencies of E, F1, and F2 regions respectively. True height analysis of the quarter hourly ionograms shows maximum eclipse associated decrease at 200 km.
期刊介绍：
The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc.
NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR).
All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
