Observations of XTE J1752-223 (ATEL #2258) with the RXTE All-Sky Monitor show increasing intensity, with one-day averages (2-12 keV) of 57(11) mCrab on MJD 55128, 86(12) on 55129, and 145(23) on 55130
(partial day). The spectrum appear softer in the most recent measurements, suggesting a transition to the thermal state (see ATEL #2261) if the source is a black hole binary system.
