Descripción
Following the recently reported decline of the X-ray flux from the millisecond pulsar HETE J1900.1-2455 (Galloway et al. 2007, ATel #1086), we acquired images of its optical counterpart using the Wide Field Camera mounted on the 2.5m Isaac Newton Telescope at La Palma. The images were obtained on 2007 May 29 4:10-4:33 UT and May 30 3:42-4:17 UT and photometrically calibrated using the standard stars SA 113-260 and BD+33 2642.

    ANDES, the high-resolution spectrograph for the ELT: design of the adaptive optics system
    ANDES,the high resolution spectrograph for the ELT, will work both in seeing limited mode and with Adaptive Optics (AO) correction. ANDES-SCAO is a single conjugated AO system working with natural guide stars, feeding the IFU coupled to the YJH spectrograph. The main science goal of the ANDES AO mode is the characterization of the exo-planet

    HARMONI at ELT: verification tests of opto-mechanical mounts for HARMONI preoptics in cryogenic environment
    HARMONI is the high angular optical and near-IR integral field spectrograph (IFS) for the ELT. The instrument covers a large spectral range from 470 to 2450nm with resolving powers from 3300 to 18000 and spatial sampling from 60 to 4mas. A workhorse instrument designed to operate in two Adaptive Optics modes - Single-Conjugate Adaptive Optics (SCAO
