    Quadratic magnetic gradients from seven- and nine-spacecraft constellations by C. Shen, G. Zeng, R. Kieokaew, Y. Zhou

    Published 2025-01-01
    “…This study focuses on deriving both linear and quadratic spatial gradients of the magnetic field using data from the nine-spacecraft (9S/C) HelioSwarm or seven-spacecraft (7S/C) Plasma Observatory constellations. Time series magnetic measurements, combined with transformations between reference frames, were employed to determine the apparent velocity of the magnetic structure and the quadratic magnetic gradient components along the direction of motion. …”
