PG 0149+138: shortening of the superhump period

   Josch Hambsch has reported further observations.  It has become evident
that the superhump period experienced discontinuous shortening (stage B-C
transition), as suggested by the previous report.  The mean period after
Sep. 17 has been 0.08448(3) d.  Both PDM analysis and O-C analysis have
confirmed this finding.
