CSS J203937.7-042907: updated superhump period

   We have received further observations from Josch Hambsch,
Michael Richmond and Enrique de Miguel.  The refined superhump
period is 0.11077(2) d.  The timing of the superhump on the
initial night is slightly deviated from the rest, either
suggesting that it was observed during stage A or there has
been an increase in the period.  There has been no evidence
for a large negative period derivative.
