   It has now crossed the sun and has survived :-) Its luminosity is on its   
   way down. It should be continuing to dim for several more months (but   
   who knows, it isn't really following the script any more) but it has   
   already reached its dimmest value of the 20 years prior to November 2019   
   (V-magnitude over 1), though still very far from the 1.8 magnitude of   
   earlier this year.   
      
   It is hard to tell from the few data points available, but its current   
   dimming cycle seems to be even more pronounced than the previous one at   
   the same point in the cycle. So it might dim to more than a 1.8   
   magnitude this time. Who knows? I still think it is about to go super   
   nova. On an astronomical time scale, that is within the next 100,000   
   years or so.
