Galactic black hole transient H1743-322 has been in outburst since Jan 4, 2008 (ATEL #1348, #1349, #1352). We have analyzed the RXTE PCA data taken on Jan 24 and Feb 1st. Quick fits to both data sets with a power law + diskbb + smedge model were performed. On Jan 24, the photon index was 2.3. The ratio of the power law flux to the overall flux in the 3-25 keV band was 70%. The power spectrum showed weak broad band noise with 8% rms amplitude of variability.
