V877 Ara: large superhump period change!

Dear Colleagues,

    We have received new comprehensive data from Greg Bolt.  Although
the mean superhump period is around 0.0841 d, the entire observation
is no longer expressed by a single period.  The inferred period change
is an order of -2x10^(-4), which is the largest period change ever
observed in long-period SU UMa-type systems.  Further detailed observations,
esp. timing observations of superhumps, are most urgently requested
in order to confirm this unexpectedly large superhump period change!

Regards,
Taichi Kato
on behalf of the VSNET Collaboration team
