Magnetic reconnection between Interplanetary Magnetic field (IMF) and magnetosphere allows solar wind to penetrate into Earth, generating geomagnetic storms. In this work, we investigate the effects of the storm of 23rd April 2023 into middle and low latitudes using geomagnetic field data from 5 Intermagnet ground stations. We look for possible connection with physical parameters from OMNIWeb data at 1-min resolution through cross-correlation analyses. The horizontal components of the Earth’s magnetic field show correlation with IMF parameters (By and Bz) of 0.72 and 0.96, respectively, with a time-lag up to 20 minutes, depending on station. Keywords: Interplanetary magnetic field (IMF), solar wind, cross correlation, magnetosphere, horizontal components of the Earth’s magnetic field
