Description
A calibrated numerical simulation of seasons for which there are observations of the passage of active regions across the visible disk of the sun, generating a velocity signal that can be compared with the Claverie et al. (1982) observations, has yielded values of this signal for a complete solar cycle. The results obtained indicate that the periodicities of the solar surface rotation and its first harmonic are excited at the maximum phase of the cycle, in bursts of up to 20 months, and then disappear while approaching the minimum.

    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
