Dear Colleagues,
we reduced the images collected last night, with the 0.8m-f/8 telescope
(Campocatino Astronomical Observatory) when we followed this star for about 3
hours. As we have already reported early this morning to Dr. Kato, our
light-curve shows an evident modulation (probable superhumps), with a full
amplitude of less than 0.1 mag. (unfiltered CCD photometry). The signal is
clearly modulated by a period around 25 minutes (as reported by Matt Wood).
During the run the star showed a constant fading, loosing 0.05 mag during the
3+ hours.
Regards,
Gianluca Masi, Ugo Tagliaferri
