Description
Preliminary results on new CCD photometry inV andB bands of approximately 5000 stars in four overlapping fields in the globular cluster M3 are presented. The colour-magnitude diagram shows a very well-defined sequence with a small scatter, going fainter than previously published work on this cluster. The turn-off point found atV=19.1±0.2 mag and (B-V)=0.445±0.01, is slightly redder than those obtained in previous studies.

    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
