Re: ASASSN-19rx still brightening, further eclipses observed

   Now it is evident that the orbital period is slightly
less than 5 d (I'll try to obtain the exact period later).
Such a slowly rising outburst of a long-Porb system
should be an inside-out one.  Time-resolved photometry
of the eclipses will clarify the evolution of disk radius
and brightness distribution throughout the outburst
(it must be a rare chance).

   ASASSN-19rx looks very similar to V1017 Sgr (Porb=5.7 d),
which is a renowned classical + dwarf nova.
See the Nature paper:
https://ui.adsabs.harvard.edu/abs/1992Natur.358..563S/abstract

   Current observations of ASASSN-19rx are expected to be
as fruitful as this Sekiguchi's paper (or even more
in the presence of eclipses).  Spectroscopic observations
are also highly desired.
