[vsnet-alert 9319] GW Lib: refined superhump period

[Taichi Kato]

Dear all,

   In addition to Monard's new observations (as reviewed by
Imada-san), we have also received observations from Peter Nelson.
After combining observations, we have obtained a refined superhump
period of 0.05479(1) d for the interval of April 23-24.
The inferred period excess is 2.7% (a bit large for a
WZ Sge-type star?)

   The superhump signal was also present in April 22 data.
The analysis from earlier data suggests that the genuine
superhumps underwent rapid growth and period evolution
since April 21 (full evolution took place around April 23).
