Description
The neutron star X-ray transient 4U 1608-52 is often in a state of outburst (e.g. ATel #1113); the Swift/BAT light curve shows three clear outburst peaks so far in 2009. The source usually remains in a hard X-ray state during its outbursts. Here we report an X-ray state transition to a soft state around MJD 54960-75 (2009-05-09 - 24) and accompanying optical monitoring observations before and after the transition.

    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
