                         geomagnetic storm that occurred on (1314 October 2018), during 
                         deep solar minimum. We used simultaneous observations from 
                         multiple instruments, namely; ground-based Global Navigation 
                         Satellite Systems (GNSS) receivers, a Digisonde, ground 
                         magnetometers, and space-based observations from the National 
                         Aeronautics and Space Administration Global-scale Observations of 
                         Limb and Disk (GOLD) and SWARM missions. This study presents a 
                         detailed picture of the low-latitude ionosphere response over the 
                         Brazilian sector during a minor storm. Our results showed that the 
                         minor CIR/HSS-driven storm caused a positive ionospheric storm of 
                         over \∼20 TECU in magnitude. For the first time, periodic 
                         post-sunset irregularities and Equatorial Plasma Bubbles, 
                         equatorial plasma bubbles, were analyzed using GOLD FUV OI 135.6 
                         nm emission, Total Electron Content (TEC) maps, Rate of TEC index, 
                         ROTI, and TEC gradients. Fluctuations in the interplanetary 
                         magnetic field Bz and changes in the thermospheric column density 
                         ratio (\∑O/N2) are discussed as the main sources of 
                         ionospheric changes during the storm. This paper highlights the 
                         importance of monitoring and understanding the impact of Sun-Earth 
                         interactions and provides insight into the behavior of the 
                         low-latitude ionosphere during minor geomagnetic storms.",
