Descripción
U,B,V,R,I and simultaneous near infrared J,H,K light curves of the RS CVn system ER Vul are presented. A study of the mean levels compared to other years indicates that the system is highly variable, giving evidence that important changes occur over one month. Colours show an ultraviolet and infrared excess. There seems to be a contribution from a hot plasma in the observed fluxes, with temperatures between 104 - 5×104K.

    New Robotic Telescope system progress towards critical design review
    The 4m class New Robotic Telescope (NRT) is an optical facility designed to revolutionize the rapid follow-up and classification of variable and transient objects. The project is at the stage where key systems are progressing through their detailed design phases, which presents a major engineering challenge for all project partners to manage design

    Phase diversity application on the EST MCAO testbench
    Phase Diversity (PD) is a technique widely used to measure and compensate for Non-Common Path Aberrations (NCPA) in optical systems. Beyond its traditional applications, PD has found further uses in solar astrophysics, where it enhances image quality by processing multiple images to correct residual aberrations. In this work, we introduce a

    First light of the upgraded Gregor Infrared Spectrograph
    For more than ten years, the Gregor Infrared Spectrograph (GRIS) has been the infrared spectropolarimeter on the Gregor telescope since its inauguration in 2012. The instrument mainly performs polarimetric observations of the wavelength regions at 1083 and 1565nm, which have high scientific potential. There, observers can find spectral lines that
