During INTEGRAL observations of the Galactic Disk, the superluminal source GRO J1655-40 was observed with the ISGRI detector. The source was detected in 5 ~2000second long pointings between 2005-02-18 and 2005-02-19 at a flux between 3 and 4 cps in the 20-50 keV band (corresponding to approx 30mCrab). This measurement confirms that of ATEL 415 and 414, which showed that the source is slowly brightening in the 2-10 keV band.
