In order to have a better comprehension of the different phenomena occurring on the earth and the
management of a data base in real time, that is currently studied by the seven associations (IASPEI,
IAVCEI, IAPSO, IAHS, IAG, IAMAS and IAGA) of the International Union of Geodesy and Geophysics
(IUGG) and others. We propose that the Meridian of Cusco (72 W), would become a Base Meridian, the
same as the Greenwich Meridian. This is based in the entrance of the Vernal point to the Aquarius
Constellation, defining the vernal point as "a sensitive axis of maximum conductivity" as it is
demonstrated by the stability of the geomagnetic equator (inclination of the field is zero grades) in the
year 1939, calculated with the IGRF from the year 1900 up to the 2007 and it is confirmed with
tabulated data of the Magnetic Observatory of Huancayo (Peru). From that date until this year (2007)
the geomagnetic equator it is fluctuating between 12-14 South, on the other hand in the area of Brazil it
has advanced very quickly towards the north, and approximately 108 km. above the earth surface it is
located the equatorial electrojet, that is more intense during equinoxes in South America (Peru and
Bolivia).
