Descripción
GX 339-4 is currently brightening at X-ray, UV, optical and radio frequencies (ATel #1945, #1954, #1960). Our monitoring campaign with the Faulkes Telescope South (ATel #1586) gives the following recent magnitudes (light curves are below; errors are ~ 0.02 mag): 2009-02-20 (MJD 54882.65): i' ~ 16.66 (and varying by ~ 0.2 mag in 10 minutes) 2009-02-21 (MJD 54883.76): V ~ 16.94, R ~ 16.46, i' ~ 16.68 2009-03-06 (MJD 54896.76): V ~ 16.37, R ~ 15.94, i' ~ 15.50 2009-03-07 (MJD 54897.76): V ~ 16.31, R ~ 15.89, i' ~ 15.65 The source brightened by 0.6, 0.5 and 1.2 mag in V, R and i' respectively in 13 days between 2009-02-21 and 2009-03-06.

    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
