[vsnet-alert 9327] GW Lib: superhump period increased

[Taichi Kato]

Dear all,

   After a period of constant superhump period, GW Lib now shows
an indication of increasing period.  The trend became evident
on April 28.  Further intensive observations are still very
encouraged to see if the period increase reflects a smooth positive
Pdot often observed in short-period systems (but less characteristic
to WZ Sge-type stars), or a more abrupt, discontinuous change.
