Z Tau

The membership database is currently undergoing upgrading/testing. Web functions that involve an interface with the member database (webobs, etc.) may experience intermittent problems. We hope to have this issue resolved within 24 hours (by 5pm Eastern Time on October 1st or 12:00 UT). Thank you for your patience.

I think that the current observers of Z Tau, visual and CCD, must read this article:

It's clear that they all are estimating the close companion of Z Tau.

 

See current lightcurve:
