Description
On 20-21 October 2005, the remaining six Chandra/HRC-I observations (as mentioned in ATEL #637) were performed as part of the XMM-Newton/ Chandra monitoring campaign of the 1.7 square degree region around Sgr A* (Wijnands et al. 2005, A&A submitted, astro-ph/0508648). The neutron star X-ray transient SAX J1747.0-2853 was in the field-of-view of one of these observations and we detected the source at a 2-10 keV luminosity (at a distance of 8 kpc) of ~8E35 erg/s (obtained using PIMMS and assuming an absorbed power-law model with a column density of 7E22 cm^-2 and a photon index of 2; uncorrected for vignetting effects).

    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
