CC Scl: unstable superhumps?
We have received observations from Josch Hambsch on three nights.
Relatively low-amplitude (up to 0.1 mag) variations were recorded.
Although the waves were not coherent, the strongest signal (likely
period) was at 0.0603(2) d. The mean amplitude folded by this
period was 0.13 mag. The period in quiescence was reported to be
0.0584(2) d (Tappert et al. 2004, MNRAS 354, 321) and the current
variation appears to be superhumps, although the profile is not
as regular as in other SU UMa-type dwarf novae. Further observations
are still encouraged!
