BF Ara data from Peter Nelson

Dear Colleagues,

    We have received new data on BF Ara (Aug. 23 and 25) from Peter Nelson.
The first set of the data shows 0.1 mag superhumps.  On Aug. 25, the
amplitude of superhumps decreased to 0.05 mag, and the profile becomes
more complex.  The object may be entering the rapid decline stage, or
may be currently experiencing a stage of reduced superhump amplitude
before the final decline (seen in some SU UMa stars).  In the latter case,
superhumps are expected to grow again.  Determination of the contribution
from the secondary superhumps is also very important.  Please continue
the excellent coverage as long as the object is observable!

Regards,
Taichi Kato
