Description
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).
