    Magnetic topology of quiet-Sun Ellerman bombs and associated ultraviolet brightenings
    Context. Quiet-Sun Ellerman bombs (QSEBs) are small-scale magnetic reconnection events in the lower atmosphere of the quiet Sun. Recent work has shown that a...

    Magnetic topology of the north solar pole
    The magnetism at the poles is similar to that of the quiet Sun in the sense that no active regions are present there. However, the polar quiet Sun is somewhat...
