    Fried's parameter derived from observations of granulation outside the disk centre
    A new method has recently been developed to obtain the Fried's parameter from observations of granulation outside the disk center, based on the different...

    Granulation deformation near and in sunspot regions
    High-resolution white-light pictures are analyzed to study the differences between the granular size near sunspot penumbrae and in light-bridges presenting...

    Magnetic aspects of the evolution of sunspots
    The spectroscopic determinations of the solar magnetic fields are based on the Zeeman effect observed in relation to a number of absorption lines of the solar...

    Magnetic bright points in the quiet Sun
    We present a visual determination of the number of bright points (BPs) existing in the quiet Sun, which are structures though to trace intense kG magnetic...
