PU CMa time-series analysis

Dear Colleagues,

   Based on the data mainly on Feb. 14, we have detected small-amplitude
(0.03 mag) variations likely associated with the orbital (or superhump?)
signal.  The best period was around 0.053 d, which is shorter than the
orbital period.  It may have been possible some sort of "negative superhumps"
transiently appeared during this stage.  Further analysis of the received
and incoming data is in progress.  Torii-san reported that the object
was around mag 12.4 last night.

Regards,
Taichi Kato
