The Embrace Magnetometer Network for South America: First Scientific Results

Abstract

The present work is the second of a two-part paper on the Embrace Magnetometer Network. In this part, we provide some of the first scientific findings that we have already achieved with this network. We identified the diurnal and the seasonal natural variations of the H component. We provided the precise determination of sudden storm commencements and sudden impulse. We showed that the H amplitudes derived from the Embrace MagNet during intense magnetic storm are in very good agreement with the Dst index. We showed that it is possible to investigate the effects on the solar quiet ionospheric current systems as a response to the X-class solar flares occurring during daytime under magnetically quiet conditions. Plain Language Summary This manuscript is the second of a two-part paper and provides the reader with the first scientific findings from the new Embrace Magnetometer Network (Embrace MagNet), which is located in South America and is based on fluxgate magnetometer. The main purpose of this network is to fulfill the gap in magnetic measurement, which are suitable for space weather purpose. Details on the network description and its qualification are provided in the first paper.
