The transient IGR J17191-2821 (Atels #1021,#1022,#1025) has reached a state of increase activity demonstrating a bright outburst. During RXTE/PCA bulge scan observations taken on April 29 (14:39:50 UTC) and May 2 (16:30:43 UTC) the source was detected at a level of ~30 and ~70 mCrab (2-10 keV), respectively. During a Swift/XRT TOO observation (1 ksec) on May 1 (13:03:20 UTC) we detected the source at a high level of ~1.2E-9 erg/sec/cm^2, corresponding to ~ 46 mCrab (absorbed 2-10 keV flux).
