Z Cha: fully developed superhumps and stage A superhumps

   Josch Hambsch has reported further observations.
It has become evident that the superhump grew quickly
from Apr. 19 to 20, and that the precursor part lasted
for three days.  An analysis of the first two nights
yielded a period of 0.0784(1) d.  This period of
stage A superhumps corresponds to q=0.15.
