Description:
In Vietnam, at Hue (16.4°N, 107.6°E) and Hoc Mon (10.9°N, 106.6°E), are located two GPS receivers specially
modified for recording, at a sampling rate of 50 Hz, the phase and the amplitude of the L1 signal and the Total
Electron Content (TEC) from L1 and L2. In April 2006 both the receivers have observed post-sunset scintillation
inhibition when moderate magnetic storms occurred. These measurements together with a 3D plus time imaging
of the ionosphere produced by the Multi-Instrument Data Analysis System (MIDAS) have revealed interesting
features that will be described in the present paper. In particular, the results confirm the role of the ring current
on the generation of the equatorial F layer irregularities of scale size from less than a hundred meters to a few
kilometers, highlighting also its important role in inhibiting scintillation during the storm. The characterization
of the different conditions of the Interplanetary Magnetic Field (IMF) will be illustrated, as well, to attempt a
description of the scintillation effects over a region scarcely investigated in the open literature.
