Descripción
We report the likely optical ID of the bright transient recently discovered in M31, CXOM31 J004253.1+411422 (Henze et al, ATEL #2356). With a peak X-ray luminosity of nearly 5e39 erg/sec, this is the brightest X-ray transient yet found in M31. An approximately 4000 second HST exposure on 21 Jan 2010, using the ACS and F435W filter, finds an apparently new object with m(f435w)=23.8. This object is not seen in an earlier serendipitous 4000 second ACS exposure on 13 October 2004 using the F660N filter.

    ANDES, the high resolution spectrograph for the ELT: science goals, project overview, and future developments
    The first generation of ELT instruments includes an optical-infrared high resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion Echelle Spectrograph). ANDES consists of three fibre-fed spectrographs ([U]BV, RIZ, YJH) providing a spectral resolution of ∼100,000 with a minimum simultaneous wavelength

    An overview of the preliminary optical design of the European Solar Telescope (EST)
    The European Solar Telescope (EST) is a 4-m class-solar telescope that will become part of the next generation of groundbased facilities. Located at the "Observatorio del Roque de los Muchachos" in La Palma (Spain), it will be aimed to study the magnetic connectivity of the solar atmosphere with high spatial and temporal resolution. The EST optical

    ANDES, the high-resolution spectrograph for the ELT: UBV spectrograph preliminary design
    We present the design of the ANDES UBV module, the bluest spectrograph of the ANDES instrument. It is a fiber-fed high resolution, high stability spectrograph, which will be installed on the ELT-Nasmyth platform to minimize blue fibre losses from the focal plane to the spectrograph. In this paper we present the status of development of the
