The RCB star Z UMi is fading again after recovering from its most recent deep fade. Interestingly, Z UMi did not recover to its historical high value before this fade began, missing it by some 2 magnitudes. From the light curve http://tinyurl.com/bn7ycw9 it appears that the 'normal' high value is trending downward. Could it be that Z UMi is going into a very prolonged fade similar to that of R CrB itself http://tinyurl.com/cfqaems which has been in a low state for some 6 or 7 years?

Observed it last week at 14.9. Hoping to catch one more glimpse tonight (if it will ever clear up!) before it fades below the range of my 15 inch.
