   Berto kindly provided the data.  They were indeed superhumps.
I obtained a superhump period of 0.0947 d, which gives a slightly
large (6.5%) fractional superhump excess.  Although this period
obviously requires future confirmation, the large excess might
suggest a rather massive secondary.  Combined with the literature,
I selected the most likely orbital period of 0.0889195, but there
still remains ambiguity in the cycle count.  Future observations
are naturally wanted!
