[vsnet-alert 19811] RZ LMi up to now

RZ LMi up to now

   Let's see the interesting features of our RZ LMi
campaign up to now.

   The object may be entering a standstill, or it may be
a very prolonged superoutburst.

   There is a short precursor around the final rise
to the second superoutburst (at 57484, upper panel).
Lasso frequency analysis (quick-look result, lower panel)
shows superhumps.  The dash represent Porb in RKCat (probably
not correct).  There seems to be an excursion to higher
frequencies when the object faded (this may be an emerging
signal of the orbital period).
The Lasso analysis is not sensitive to stage A superhumps
and this part of the figure can be neglected.
It would be interesting to see the frequency evolution,
and we apparently need more coverage.
Let's hope there are more observations are reported
after examining this figure.
