The Eclipsing Cataclysmic Triple System V471 Tau
The precataclysmic variable V471 Tau was monitored photoelectrically in U, B, V and R colours since 1994 during 21 nights at the Skalnaté Pleso, Stará Lesná and Kryonerion Observatories. The new times of minima had been derived. They may suggest that the cause of the (O — C) curve may be more complicated than what would correspond to the light-time effect only. The next season 2002/2003 will be crucial for definite confirmation of the behaviour of the (O — C) diagram of V471 Tau.
