  The black hole candidate XTE J1817-330 was discovered in outburst on 26
January 2006 with RXTE/ASM. One year later, on 28 February 2007, another X-ray
transient discovered in 1996, XTE J1856+053, was detected by RXTE during a new
outburst. We report on the spectra obtained by XMM-Newton of these two black
hole candidates.
