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.

Taichi Kato
