Coincidentally and suitably with the end of the visibility in Europe, the V/R activity in zeta Tau is almost dead.
This situation does recommend now a period analysis for the time span February 1995 to March 2012. The results (a pro/am collaboration) of the period, To, K1 and rms are to find in the attached fig.
We have to wait and see, whether the V/R activity will start again in the future. Thanks a lot to all the ARAS members for their spectra and contributions. A paper as observation report has been submitted at IBVS.
