<div>As a preliminary step to install the First Magnetic Observatory of
Honduras, the local geomagnetic components are being computed in
Tegucigalpa, Honduras (TEG), for the temporal interval 2010 –2013,
using the Tsyganenko and Sitnov 2005 (J. Geophys. Res. 110, A03208,
2005: TS05) semi-empirical magnetospheric model. The diurnal variation
of H (Sq) is obtained from the Chiripa Observatory (Costa Rica) data,
using the International Quiet Days and the Normal Orthogonal Component
Analysis. Pearson’s correlation coefficients are calculated between the
H-component computed with the TS05 model in the Tegucigalpa coordinates
and the Chiripa Observatory (CRP) data. The best correlations are
obtained in days with Kp &lt; 4, when the Sq and the quiet daily
variation are removed from the CRP-H data and the TEG-H-component
respectively. Seven TS05 magnetospheric currents are obtained in order
to evaluate their contribution to the Sq. Using the Normal Orthogonal
Component Analysis, the Chapman-Ferraro current fits better in the
0.00–12.00 local time interval, and the Birkeland currents fit better
in the 12.00–24.00 local time interval.</div>
