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, 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%;" lang="PT-BR" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%;"> </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%;" lang="PT-BR" data-mce-style="mso-bidi-font-size: 12.0pt; line-height: 115%;">Convener: Paulo R.
