An XMM-Newton observation of the luminous Seyfert galaxy PG1211+143 in 2001revealed the first clear evidence for a highly ionised high speed wind (in anon-BAL AGN), with a velocity of v~0.09c based on the identification ofblue-shifted absorption lines in both EPIC and RGS spectra. A subsequentanalysis of EPIC spectra, including additional absorption lines, led to anupward revision of the wind speed to ~0.14c, while broad band modellingindicated the need for a second, partial covering absorber to account forcontinuum curvature and spectral variability. We show here, in a new analysisof the XMM-Newton RGS data, that this additional absorber is detected in thesoft X-ray spectra, with the higher spectral resolution providing a muchimproved velocity constraint, with v~0.07c. Similar variability of the 0.07cand 0.14c outflow components suggest they are physically linked, and wespeculate that occurs by the fast (primary) wind impacting on small clumps ofhigher density, slow moving matter close to the disc. We show that strong,velocity broadened soft X-ray emission features, located at the redshift ofPG1211+143, indicate the extended scale of the ionised outflow.
