The RXTE/PCA Galactic Bulge scans, however, show a decrease of the source at lower energies (2-10 keV), from 840 mCrab on Feb 9 to 710 mCrab on Feb 12 to 670 mCrab on Feb 15 (all +/-4 mCrab). This is in contrast to the spectral behaviour described above.
These findings may indicate a state change, which could be accompanied by changes in the emission at other wavelengths. We again note that an INTEGRAL ToO observation of XTEJ1817-330 is presently ongoing and will last up to Feb 17, 11:20 UTC. Observations at other wavelengths are therefore encouraged.
