  SDSS J155644.24-000950.2 has apparently stopped fading rapidly.
Nakajima-san's most recent observation on Aug 11 showed the object
only 0.18 mag fainter than on the previous night.
Such "dip"-like fadings are frequently observed in WZ Sge-type
stars, but are rarely seen in long-period SU UMa-type dwarf novae.
Superhumps were still present.

  Observers are strongly urged to continue observing this object
since the present behavior is atypical for an SU UMa-type dwarf
nova with this orbital period.
