The Solar Orbiter spacecraft travels behind the Sun from the Earth’s perspective. This means that it allows scientists, for the first time, to see the magnetic fields on more than half of the Sun at a time. This is important because the Sun’s magnetic field shapes its atmosphere and the solar wind, charged particles that stream away from the Sun and fill the solar system. To model the space environment near Earth and throughout the solar system, it is essential to know the magnetic field on the entire surface of the Sun.



We combined observations from Solar Orbiter with measurements from the Earth to create a model of the magnetic fields covering the Sun’s surface. We validate the use of multiple data sources in a single full-Sun map and investigate periods when Solar Orbiter observed the emergence and decay of magnetic fields not visible from the Earth. Solar Orbiter’s unique perspective results in a better characterization of the Sun’s magnetic field and improves models of the solar wind that benefit scientific investigations and future modeling of the Earth’s space environment.
