n this paper,
we present the features of the equatorial F
-
region current systems over equatorial Africa during nighttime on
05
th
August, 2001 observed at midnight. The observations have inferred from in situ CHAMP satellite measurements of the
vector magnetic field. The magnitudes of the current along all the three magnetic field components
of the Earth’s
magnetic field
varied considerably. The B
x
-
component recorded a diamagnetic effect of about 8nT, B
y
-
component recorded a
current density of 5mA/m, and B
z
-
component reached a value of 3mA/m. The F
-
region dynamo, gravity dynamo and plasma
-
pressure gradients are the possib
le mechanisms for the occurrence of these currents. The signatures confined to the equatorial
region bounded by the Appleton anomaly
