[vsnet-alert 22821] ASASSN-18aan: updated period

[Kojiguchi Naoto]

Sjoerd Dufoer, Tamas Tordai, Itoh-san, Tonny Vanmunster,
and Sergey Shugarov have reported further observations.

we have obtained a refined superhump period of 0.1658(1) d
and a refined orbital period of 0.14944(3) d. Now, this object
has reached V=15.2.

The humps seem to be growing now. The O-C diagram
indicates the object now might show stage A superhumps.

As reported in vsnet-alert 22806, 22816, and 22817,
this object shows a very unique state. Therefore, further
observations are strongly encouraged.

If possible, time-resolved observation with multicolor will be
good (e.g. V + Ic bands). A most important condition is,
of course, the qualitykeeping of the light curve profile.
And because this object might be an SU UMa-type dwarf nova,
not only observations inside eclipses, but observations outside
eclipses are also needed.
