Abstract
The eleventh generation of the International Geomagnetic Reference Field (IGRF) was adopted in December 2009 by the International Association of Geomagnetism and Aeronomy (IAGA) Working Group V-MOD.It updates the previous IGRF generation with a definitive main field model DGRF 2005.0, for 2005.0, a main field model IGRF 2010.0, for 2010.0, and a linear predictive secular variation model for 2010.0-2015.0.In this note the equations defining the IGRF model are provided together with the spherical harmonic coefficients for the eleventh generation.Maps of the magnetic Declination, Inclination and Total Intensity for epoch 2010.0 and their predicted rate of change for 2010.0 -2015.0 are presented and the recent evolution of the South Atlantic Anomaly and magnetic pole positions are examined.
