  This paper presents the first results of a new Arar-magnetometer station
located (Geographic Coordinates: 30 58.5 N, 41 2.3 E) at Northern Border
University in Saudi Arabia. The geomagnetic response detected by the station
during a moderate magnetic storm of April 20, 2018, is examined as an initial
study. The total magnetic field components measured by the station showed a
prompt increase in coincident with the Sudden Storm Commencement (SSC) time
measured by ACE satellite. The high rate of magnetic field digital data system
of Arar-Magnetometer station with a sampling rate of 0.1 s allowed us to study
the geomagnetic pulsation at the northern region of the Arabian Peninsula for
the first time.
