The electric field in the E region was measured with a dipole sensor on two rocket flights over Manitoba, Canada, results being obtained 1-1/2 and 2-1/2 hr before local midnight in an altitude range of 115-165 km. Under quiet conditions and in the presence of a diffuse, east-west 2 kR auroral arc, the predominant vector component of the electric field was also quiet and between 35 and 40 mV/m perpendicular to the magnetic field, southward. Parallel to the magnetic field, the vector component increased from -17 mV/m at 130 km, reversed direction at 160 km during the latter third of the flight and fluctuated around +6 mV/m between 155 and 135 km on the descent. Under disturbed conditions during the recovery phase of a large magnetic storm, the electric field was also more disturbed, but there was no significant electric field along the geomagnetic field.
