Description
We present observations of the full Stokes vector in a flaring region, taken in the chromospheric He I 10830 Å multiplet. The data were recorded with the new Tenerife Infrared Polarimeter (TIP 2) at the German Vacuum Tower Telescope (VTT) during May 2005. The He profiles during the flare are extraordinary, showing extremely broad Stokes I absorption and very complex and spatially variable Stokes V signatures. We give first results on the line-of-sight velocities and the magnetic field vector values in the chromosphere for one observed Stokes profile by applying an inversion code to the He I lines.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    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
