ASASSN-16eg: WZ Sge-type dwarf nova with a very long Porb?

   Tonny Vanmunster, Kyoto team, Tamas Tordai and Arto Oksanen
have reported observations.  The identification of
early superhumps now appears to be secure.
The period is 0.07554(3) d with double-wave modulations
(full amplitude 0.06 mag).
A WZ Sge-type dwarf nova with the Porb may be
a candidate for a period bouncer (although such
an object may be too extreme).
Further observations will allow us to identify
stage A superhumps and eventually the mass ratio
and we hope we can characterize this very unusual object.

   Tonny apparently failed to post the following message
to vsnet-alert.  It is from

Dear colleagues,



Tonight (2016, Apr 10/11), I have been running an unfiltered CCD photometry
session of ASASSN-16eg at CBA Belgium Observatory,  using a 0.35-m f/6.3
telescope and STT-3200ME CCD camera, under clear skies. The resulting light
curve clearly shows the presence of double-waved early superhumps. This
establishes this target as a new WZ Sge-type dwarf nova. The amplitude is
approx 0.15 mag. A preliminary period analysis using the ANOVA,
Lafler-Kinman and PDM methods (Peranso), yields a combined period of 0.0736
+/- 0.0007d (106 min). The object is currently bright at mag 12.7
(unfiltered).



Observations will be sent to CBA and VSNET for further analysis.



It is evident that additional  observations of this interesting new target
are urgently needed.

Best regards
Tonny
