[en] The cluster NGC346 is the largest star formation region in the SMC. It contains a large fraction of the early-type O stars of this galaxy. In the outskirts of this cluster lies HD 5980, a unique system of massive stars of which one component underwent a LBV-type eruption in 1993. The XMEGA consortium has obtained one deep (100 ks) Chandra exposure of NGC 346. It shows ~70 point sources, of which only half possess an optical counterpart; strong emission from HD 5980; and diffuse emission associated with the cluster and SNR 0057-7226.
