Equatorial ionosphere strongly responds to magnetospheric and atmospheric events, as well as to disturbances in the high and sub-auroral thermosphere-ionosphere system. Recent multi-instrument and multi-site observations, as well as, theoretical and simulation investigations have advanced our understanding of these phenomena, both during geomagnetic quiet and disturbed periods. The objective of this symposium is to bring together experimentalists and theoreticians to survey the latest results, examine new ideas and concepts, to join forces of researchers in high-, mid-, and low-latitude ionosphere and to indicate important future directions in equatorial and low-latitude research.</span></p><p class="MsoNormal" style="text-align: justify; line-height: 115%;" data-mce-style="text-align: justify; line-height: 115%;"><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif';" lang="PT-BR" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif';"> </span></p><p class="MsoNormal" style="text-align: justify; line-height: 115%;" data-mce-style="text-align: justify; line-height: 115%;"><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif';" lang="PT-BR" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif';">C</span><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif'; mso-ansi-language: EN-US;" lang="EN-US" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif'; mso-ansi-language: EN-US;">onvener: Maxim Klimenko, </span><span lang="PT-BR"><a href="mailto:maksim.klimenko@mail.ru" data-mce-href="mailto:maksim.klimenko@mail.ru"><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif'; mso-ansi-language: EN-US;" lang="EN-US" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif'; mso-ansi-language: EN-US;">maksim.klimenko@mail.ru</span></a></span></p><p class="MsoNormal" style="text-align: justify; line-height: 115%;" data-mce-style="text-align: justify; line-height: 115%;"><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif'; mso-ansi-language: EN-US;" lang="EN-US" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: 'Arial','sans-serif'; mso-ansi-language: EN-US;">Co-conveners: </span><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;" lang="EN-US" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;">Archana Bhattacharya, </span><span lang="PT-BR"><a href="mailto:abh@iigs.iigm.res.in" data-mce-href="mailto:abh@iigs.iigm.res.in"><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;" lang="EN-US" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;">abh@iigs.iigm.res.in</span></a></span><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;" lang="EN-US" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;">; Biqiang Zhao, </span><span lang="PT-BR"><a href="mailto:zbqjz@mail.iggcas.ac.cn" data-mce-href="mailto:zbqjz@mail.iggcas.ac.cn"><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;" lang="EN-US" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;">zbqjz@mail.iggcas.ac.cn</span></a></span></p><p class="MsoNormal" style="text-align: justify; line-height: 115%;" data-mce-style="text-align: justify; line-height: 115%;"><span style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;" lang="EN-US" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%; mso-ansi-language: EN-US;"> </span></p></BODY></HTML>
