Abstract (from CDS):
In addition, BW Sculptoris shows a transient but powerful signal with a period near 87 min, a quiescent superhump. The ∼ 11 per cent excess over the orbital period is difficult to understand, and may arise from an eccentric instability near the 2:1 resonance in the accretion disc.
