Abstract

In the framework of the INTEGRAL observations of the Galactic Inner Disc, we obtained the first hard X-ray detection above 20 keV of the source SAX J1806.5-2215 (in't Zand et al. 1998, NuPhS, 69, 228). The currently on-going outburst (ATels #3202, #3193) of this so-called "burst-only" source (Cornelisse et al. 2004, NuPhS, 132, 518) has been detected by INTEGRAL on 2011 March 06 from 10:01 to 23:21
