Query: CC Sculptoris: A superhumping intermediate polar   We present high speed optical, spectroscopic and Swift X-ray observations
made during the dwarf nova superoutburst of CC Scl in November 2011. An orbital
period of 1.383 h and superhump period of 1.443 h were measured, but the
principal new finding is that CC Scl is a previously unrecognised intermediate
polar, with a white dwarf spin period of 389.49 s which is seen in both optical
and Swift X-ray light curves only during the outburst. In this it closely
resembles the old nova GK Per, but unlike the latter has one of the shortest
orbital periods among intermediate polars.
