Dear Colleagues,
I managed to follow this star all night and I was finally
able to possibly spot emerging superhumps. My three nights
are available here:

during the third night the curve evolved dramatically, at
the end showing a more typical profile, a larger
amplitude... but still on a fading trend.
I managed to find a possible period candidate for the
modulation, using the PDM technique after detrending the
data. Using all the nights I get P=2.3853h; using only the
last two nights I get the same value.
Data will be send to Kyoto for a better analysis.
Good night,
Gianluca
