Its light displays an orbital phase coupled variability with a peak-to-peak amplitude up to 0.04mag. The photometry available and new high dispersion spectra were investigated from a point of view of CP characteristics. A series of high resolution high S/N coude spectra was acquired from which 25 weak to strong unblended lines of Fe I and II, Ti II, Cr II, Zr II, and Ba II were selected to study spectral line variability. Two Zeeman spectra were obtained to search for a possible magnetic field of the star, and one echelle spectrum in a wide spectral region was analysed for abundance determination by means of synthetic spectra. The photometric observations were subjected to a PCA disentangling of the complex photometric behaviour. Description: The twenty-nine spectra from the National Astronomical Observatory, Rozhen, Bulgaria (NAO), were recorded using the photometric AT200 CCD camera with a SITe SI003AB 1024x1024 detector placed at the 3rd optical camera of the coude spectrograph of the 2m RCC telescope, with R=22000, between 14/06/2005 and 03/05/2009.
