ASASSN-18ey = MAXI J1820+070: slowly fading and periodic variations ?

           Josch Hambsch, Klaus Wenzel, Tamas Tordai, Hiroshi Itoh,
Tonny Vanmunster, Kyoto U. team, Michael Richmond,
Stephen Brincat,  reported new observations.
This source is slowly fading and the current magnitude is 14.0 mag.
I performed the period analyses, and might find ~0.679-days period
and ~0.1-mag amplitude variations.  However, I don't know
this kind of variations is real.  The superhumps in the main outburst
had ~0.69-days period, and the detected period is a few percent
shorter than that period.
Further photometric observations are encouraged, and thank you for
your cooperation.

Kind regards,
Mariko Kimura
