SAX J1711.6-3808 is a transient X-ray source which was seen active for the first time in January through May 2001. It was moderately bright, indicating sub-Eddington accretion levels throughout the outburst. The Galactic latitude, brightness and spectrum identify SAX J1711.6-3808 as a Galactic X-ray binary; optical confirmation proves difficult because of the large extinction. The lack of type-I X-ray bursts and coherent oscillations, and the exhibition of a broad Fe-K emission feature suggest that the primary in SAX J1711.6-3808 is a black hole.
