The light curves span 12 years and  show long-term periodicities (SMC-SC3) and modulated eclipses (SMC-SC4) that are discussed in terms of wide-orbit intermediate mass interacting binaries and associated  envelopes. SMC-SC3 shows a primary period of 238.1 days  along with a complicated waveform suggesting ellipsoidal variablity influenced by an eccentric orbit.
