as complement to our publication in A&A 560, A30 (2013), we can notice today that a new V/R activity cycle has started. That means that the monitoring of the V/R ratio will be continued in order to confirm our found period of 84.2 day (+/- 2).
our current monitoring of the Halpha V/R shows a periodic behavior (period = 42d), that does not fit to the periodicity we observed from 10/2004 to 01/2020 (period = 84.2d) (see link below).
The current period, the half of 84d, can´t be explain at present, which is why observations are very urgent. It would be great, if interested obeserver could take at present spectra as much as possible.
