Query: First Magdas Equipment In Ecuador   The Magnetic Data Acquisition System (MAGDAS) was installed in the protected
Jerusalem Park in Malchingui-Ecuador in October of 2012, under the joint
collaboration between Kyushu University of Japan and the Quito Astronomical
Observatory of the National Polytechnic School of Ecuador. In this paper, we
describe the installation process and present the preliminary data obtained
with the MAGDAS equipment. The behavior of the four components, D, H, Z and F
allow us to see the importance of having the Ecuador station where the magnetic
field has not been systematically measured before, in valuable contribution to
study of the equatorial atmosphere.
