Description
Velocity measurements of disk integrated sunlight obtained by GOLF experiment aboard SOHO are used to find the parameters of solar p-modes (l <= 3 and 9 <= n <= 26) allowing the comparison of mode parameters at maximum and minimum of the solar activity. Series of data are taken at two different epochs: 1996 and 2000. A clear shift in frequencies have been detected in agreement with previous works. No change in the splittings has been obtained at maximum and minimum. Also the ratio between component's power in a given multiplet has been calculated for modes l = 2 and l = 3.

    NEOMIR: ESA's space-based infrared mission for NEO detection and early warning
    The Near-Earth Object Mission in the Infra-Red (NEOMIR) is the first ESA's space-based mission fully dedicated to discovering near-Earth objects (NEOs), with a focus to detect and raise early warning for the smaller objects that are coming from the Sun direction, thus nearly impossible to be detected by ground-based optical survey. NEOMIR is

    Upgrading the polarisation modulation unit of the Gregor Infrared Spectrograph
    The Gregor Infrared Spectrograph (GRIS) is installed at the Gregor telescope at Observatorio del Teide, Spain. The instrument started observations in 2012 and underwent several upgrades in the following years. Currently, it is experiencing the most significant upgrade so far, which includes, among other things, adding two optical channels to
