ASASSN-18ey = MAXI J1820+070: plateau phase

      Josch Hambsch, Klaus Wenzel, Tamas Tordai, Hiroshi Itoh,
Tonny Vanmunster, Seiichiro Kiyota, Kyoto U. team,
Stephen Brincat, Kenji Hirosawa reported new observations.
This source was gradually rising over ~10 days, and now enters
a plateau phase.  The current magnitude is ~13.8.
There are no significant variations now.
According to MAXI team members, the X-ray spectrum still shows
the low/hard state, and the averaged X-ray flux is constant.
Further observations are encouraged, and thank you for your
cooperation.

Kind regards,
Mariko Kimura
