    World Magnetic Model update
    From: Paul Hirose
    Date: 2019 Jan 10, 13:41 -0800

    Rapid change of Earth's magnetic field has forced an update to the World
    Magnetic Model earlier than expected.
    "The most recent version of the model came out in 2015 and was supposed
    to last until 2020 — but the magnetic field is changing so rapidly that
    researchers have to fix the model now. “The error is increasing all the
    time,” says Arnaud Chulliat, a geomagnetist at the University of
    Colorado Boulder and the National Oceanic and Atmospheric
    Administration’s (NOAA’s) National Centers for Environmental Information."
