    "abstract": "We discuss the measurements of the main parameters of the ionospheric\nresponse to the total solar eclipse of June 21, 2001. This study is based on\nusing the data from three stations of the global GPS network located in the\narea of the totality band in Africa. This period was characterized by a low\nlevel of geomagnetic disturbance (the Dst-index varied from -6 to 22 nT), which\nalleviated greatly the problem of detecting the ionospheric response to\neclipse. An analysis revealed a clearly pronounced effect of a decrease\n(depression) of the total electron content (TEC) for all GPS stations. The\ndelay between the smallest value of the TEC with respect to eclipse totality\nwas 9-37 min. The depth and duration of the TEC depression were 0.5-0.9 TECU\nand 30-67 min, respectively. The results obtained in this study are in good\nagreement with earlier measurements and theoretical estimations.",
