OT J213806.6+261957: period decrease stopped

   According to observations by Enrique de Miguel, the period decrease
has apparently stopped.  The mean period since June 23 has been 0.05480(2) d.
These signals are likely long-enduring superhumps during the post-superoutburst
stage of a WZ Sge-type dwarf nova.  Further observations are encouraged
to see how this period evolves (stable periodicity as in GW Lib or else?).
