Description
The decay of a small solar active region is studied with high-resolution magnetograms. The reduction process made it possible to match intensity and magnetic pictures exactly. It is found that the granulation massages the magnetic concentrations and contributes to their fragmentation. Supergranules contribute to the decay of the pore by removing fragments from their formation site. Also, it is shown that subarcsecond magnetic features form a small-scale magnetic network. A probable example of pure submergence is observed in which a pair of oppsite polarity features attract each other and vanish.

    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

    Small-ELF Telescope opto-mechanical system: progress on design, manufacturing, and tensegrity prototyping
    Small-ELF (SELF) is a 3.5-meter telescope currently entering the manufacturing phase and will serve as a technology precursor for the much larger telescope named ELF (Exo-Life Finder). The primary objective of the proposed design approach is to to radically improve the system's capabilities for the detection of biomarkers and life in the
