ASASSN-19zz: very unusual variation

   Josch Hambsch and Berto Monard reported observations.
Although superhump-like modulations were present on
Oct. 31 (vsnet-alert 23680), no periodic variation
was detected on Nov. 4.
On Nov. 7 and 8 (Hambsch's data), deep fadings
up to 2 mag were recorded.  The variation did not
seem to be periodic and too broad for eclipses.
More observations are needed to clarify the nature.
