Abstract The X-ray transient IGR J17191-2821 was detected by INTEGRAL (ATEL #1021) and shown to have a rapid variability and decay (ATEL #1022, ATEL #1025). A more recent report of activity by RXTE and Swift (ATEL #1065) has revealed X-ray bursts, identifying this source as a neutron star system. Recent PCA data suggests a decline from outburst peak. In an RXTE PCA observation on 2007 May 4 (01:33 UTC), we detect a 2-10 keV persistent flux level of about 85 mCrab.
