The RXTE PCA instrument has observed and detected the transient IGR
J17497-2821 (ATEL #885).
A pointed observation was taken at 04:20 UTC on Sep 20, 2006, with an
exposure of 6.6 ks. The source is detected with a flux of about 35
mCrab (2-10 keV), after accounting for the diffuse and point sources
within the PCA field of view (about 10 mCrab). No strong pulsations or QPOs
were detected, but there was strong red noise variability dominated
by periods longer than 1 second.
The PCA bulge scan monitoring program covers this source twice weekly.
The 2-10 keV fluxes on Sep 13.43, 17.24 and 20.36 (UTC) were <3
mCrab, 4.4 +/- 1.8 mCrab, and 38 +/- 4 mCrab, respectively (all error
bars and upper limits are 1 sigma). Between Sep 1 and Sep 13, the
source was not detected above ~3 mCrab (2-10 keV).
