ASASSN-18lc: superhump periods

   Berto Monard and Josch Hambsch have reported new
observations.  There was an apparent stage transition
(A-B) on June 3 and the period reported in
[vsnet-alert 22217] was spurious due to the combined
analysis of stage A and B superhumps.

   The current period (stage B) is 0.06480(2) d.
The period before June 3 (short nightly runs, and
the alias corresponding to the current period is
selected) is 0.06627(3) d (stage A).

   The long superhump period for the outburst
amplitude and slow growth of stage A may suggest
a period bouncer.  Further observations are
encouraged.
