abstract = "In the present work, we aim to analysis the result of South
America Disturbance Ionospheric Index Map (DIXSAMAP) during the
intense magnetic storm of March 2015. The DIXSAMAP was built to
analyze the ionospheric response to magnetic disturbance through
of the TECMAP data available in Embrace-INPE program. This index
covers the latitudinal range from 10 °N up to 60 °S and the
longitudinal range from 90°W up to 30 °W, with 5° of resolution in
both coordinates. We have chosen the intense magnetic storm
occurred on March 2015 (-223 nT), our results is indicating that
the ionospheric disturbance spreads from equatorial to low
latitudes regions. It interestingly to highlight that the main
disturbances are occurring during the recovery phase, mainly in
the neighborhood of the Equatorial Ionization Anomaly. Further
investigations must be done in order to identify the physical
mechanism of such disturbances.",
