Analysis of the last three RXTE observations of IGR J17091-3624 on Feb. 18 22:39 UT, Feb. 19 18:16 UT and Feb. 20 00:23 UT show fast evolution of the source variability properties. Namely, quasi-periodic oscillations (QPO) frequency, initially reported at 0.1 Hz on Feb 14 by Rodriguez et al. 2011, Atel #3168, is observed at 0.34, 0.45 and 1.66 Hz on Feb 18,19 and 20 correspondingly. In addition, during the last observation the second QPO harmonic is observed at ~3.3 Hz.
