Descripción
We report on the RXTE follow up observations of the black hole candidate IGR J17091-3624 (ATEL #3144, #3159, #3167, #3203) after the report of mHz quasi-periodic oscillations (QPO -- ATEL #3225) and 'heartbeat' oscillations similar to those of GRS 1915+105 (ATEL #3230). The 'heartbeat' oscillations first seen on March 19th (ATEL #3230) at ~25 mHz were also observed in all, except 3, of the subsequent 18 RXTE observations (see below).
