Following the strong radio flare of the X-ray binary SS433 observed with the RATAN-600 radio telescope and reported in ATel #4484, a Swift ToO was executed starting at 2012-10-15 23:45:20 UT. We obtained about 813 seconds of Swift/XRT data in windowed timing mode and measured a count rate of about 1 cts/s. The data are well fit by an absorbed power law with a photon index of 1.23. The model flux between 0.3 and 10.0 keV is 6e-11 ergs/cm^2/s. Thus, SS 433 does not currently show enhanced activity in the X-ray band, relative to past Swift-XRT observations performed between 2005-2007.
