NY Ser continues to be bright

   ASAS-SN data in March also support this.  Crimean
Astrophys. Obs. team and Kyoto U. team reported
short time-series observations, but large-amplitude
superhumps were not detected.  The object is
currently suspected to be in a "permanent superhumper"
state (but the case may be a borderline one,
since the orbital period is longer than ordinary
SU UMa-type dwarf novae).  More (longer) observations
are needed to test the presence of superhumps.
