             abstract = "Field line resonances in the magnetic pulsations frequency range 
                         named Pc 5 are known to be oscillations of magnetospheric field 
                         lines. It is observed as a combination of three fundamental modes, 
                         namely poloidal, toroidal and compressional. Such a disturbance 
                         may have their energy sources arising from external high dynamic 
                         pressure solar wind pulsation that induces waves in the day-side 
                         sector magnetosphere. Also, low-frequency instabilities of the 
                         ring current ions are candidates to promote ultra-low frequency 
                         (ULF) waves in the Pc5 frequency range. The toroidal mode is 
                         mainly due to upstream solar wind disturbances and it is observed 
                         in the dawndusk flanks, while compressional and poloidal modes can 
                         be originated from local disturbances and they can be observed 
                         everywhere in the night side sector. On July 19, 2016, at 2309 UT, 
                         the ground magnetometers registered a sudden impulse due to an 
                         interplanetary coronal mass ejection (ICME) shock arrival. The 
                         solar wind parameters registered by ACE satellite showed a sharp 
                         increase in the density and velocity, reaching 40 cm-3 and 450 
                         km/s, respectively. GOES15(13) satellite that was at noon-to-dusk 
                         (dusk-to-midnight) sector noted a major (minor) increase in the 
                         magnetic field, followed by oscillations in the horizontal 
                         magnetic field. Data from plasma parameters measured by the 
                         Themis-D satellite agreed that the geomagnetic field was 
                         compressed, the results from empirical models lead to 
                         magnetospheric standoff position compressed to 6.5 Re. In the 
                         following, results from the instruments on board the Van Allen 
                         Probes A, which traveled from midnight to dawn sector observed a 
                         relativistic electron flux dropout two orders of magnitude long, 
                         occurred throughout 3 hours following the shock arrival. The ULF 
                         waves in a Pc5 frequency range are observed both at the location 
                         of the satellite and on the ground, the different magnetometers 
                         show that ULF waves reached midi-to-low latitudes with 
                         considerable power spectral densities. Regarding the ULF waves are 
                         known to contribute with relativistic particles outward diffusion 
                         in the Van Allen belts, including through magnetopause shadowing 
                         events, we investigate the ability of the different solar wind 
                         parameters to be energy sources to generate Pc5 frequency waves in 
                         different modes deep inside the magnetosphere.",
