2.0.0 spase://SMWG/Instrument/SOHO/GOLF Global Oscillation at Low Frequencies (GOLF) GOLF 2019-05-05T12:34:56Z The Global Oscillation at Low Frequencies (GOLF) investigation will perform uninterrupted velocity oscillation and magnetic field measurements of the full solar disk, spatially unresolved, with extremely high sensitivity (<1 mm/s and 1 milligauss). To determine the velocity, the Doppler effect is measured by the resonant scattering technique. A resonant cell filled with sodium vapor in a strong magnetic field enables, by the Zeeman effect, the selective absorption of light in the two wings of the solar D lines. A comparison of the intensity on both sides of the line leads to an extremely sensitive determination of the velocity.
