RZ LMi: finally faded and possible negative superhumps

   Ian Miller's observation on late May 22 suggests
that the object started fading from the superoutburst.
It was still bright one day before.
The duration of the superoutburst (including the precursor
part) was 48 d.  Exceptionally long!

   Lasso analysis suggests the emerging evidence
of negative superhumps (at freq = 17.3 c/d).
Although Lasso is less sensitive to observational
gaps, more data from many longitudes are absolutely
desired.

   After this fading, the object is expected to show
one normal outburst and then precursor outburst
to the next superoutburst.  Stage A superhumps are
expected to appear before or around this precursor.
Continued time-resolved photometry is strongly desired.
