Variable star near NGC 4013 = SN1989Z? IAUC No. 6911 tells the discovery a variable star near NGC 4013 by D. Bettoni. The object (mag 12) lies 7" E 8" N of NGC 4013. The object may be identical with SN 1989Z (IAUC 5162). Spectroscopy by Hjorth and Benetti indicates an A-type spectrum. For more details, see IAUC 6911. The large amplitude of variation (~5 mag) and the hydrogen absorption lines at maximum may indicate this object may be a catalysmic variable caught in outburst. Follow-up observations, including time-resolved photometry, are strongly encouraged. Regards, Taichi Kato
