When I took a look at the Z Tau lightcurve today, I noticed the wide 
flat bottom in the lightcurve around magnitude 14. At the same time the 
lightcurve shows fainter than magnitude 16 observations as well. Because 
of this feature, I decided to take a good look at the available AAVSO 
close to the Z Tau position, not present on any of the other charts. I 
am afraid that many visual observers think this star is Z Tau, therefore 
the lightcurve shows a broad minimum of 14th magnitude. So take care 
that you see both the nearby magnitude 14 star and Z Tau when observing 
this variable.

Clear Skies,

Erwin van Ballegoij (BVE)
