Abstract

A summary of results of spectroscopic monitoring of the bright Be star kappa Dra carried out at the Ondrejov Observatory between 1990 and 2004 is presented. To investigate long-term variations of Kappa Dra, we focused on H{alpha}, H{beta}, H{gamma}, H{delta}, SiII 6347{AA}, SiII 6371{AA}, HeI 6678{AA}, and FeII 6456{AA} lines. We measured equivalent widths {W}, peak intensities of the double emission lines, and the central intensity of the absorption reversals relative to the adjacent continuum (I_V_, I_R_, and I_c_, respectively), and also the peak separation between violet and red peaks (Delta_nu_p). Note that {W} is taken with a negative sign for the emission line profile. Only {W}, and I_c_ were measured, of course, for the absorption lines of {HeI} and {SiII}. All measurements are collected together with heliocentric Julian dates of mid-exposures (HJDs) in Tables 2, 3 and 4.
