Fig. 1From: Evaluation of the Solar Quiet Reference Field (SQRF) model for space weather applications in the South America Magnetic AnomalyMap of geographic coordinates of the Embrace MagNet stations (stars) in the Brazilian sector, along with solid lines indicating the SAMA region (23,000 nT) and the magnetic equator. The total field intensity and the magnetic equator were obtained using the IGRF-13 for epochs 2018.0 (green) and 2010.0 (orange)Back to article page
