The detection of a high velocity (~ 0.3c) inflow of highly ionized matterduring a long XMM-Newton observation of the luminous Seyfert galaxy PG 1211+143in 2014 offered the first direct observational evidence of a short-livedaccretion event, where matter approaching at a high inclination to the blackhole spin plane may result in warping and tearing of the inner accretion disc,with subsequent inter-ring collisions producing shocks, loss of rotationalsupport and rapid mass infall. In turn, such accretion events provide anexplanation for the ultrafast outflows (UFOs) now recognised as a commonproperty of many luminous Seyfert galaxies. While the ultra-fast inflow in PG1211+143 was detected in only one of 7 spacecraft orbits, a weaker (lowercolumn density) inflow, at a much lower redshift of ~ 0.123, is revealed in thesoft x-ray spectrum by summing RGS data over the full 5-weeks XMM-Newtoncampaign. Modelling of the simultaneous, stacked pn data finds evidence for asimilar low redshift absorption component in a previously unexplained featureon the low energy wing of the Fe K emission line complex near 6 keV.  We briefly consider Doppler and strong gravity explanations for the observedredshift, with the former indicating a distant inflow feeding off-planeaccretion, where an infall velocity of v ~ 0.038c and (free-fall) radius at1400 R$_{g}$ lies beyond the tearing radius for PG 1211+143, but still withinthe sphere of influence of the SMBH. An intriguing alternative, recently givenadded credence, might be as the gravitational redshift of absorption in matterorbiting the SMBH at a radius of ~ 27 R_g. In the latter case the narrow RGSabsorption line spectrum constrains the thickness of the orbiting ring due tothe strong velocity shear so close to the hole.

Detection of low-redshift absorption in the luminous Seyfert galaxy PG  1211+143 -- a slow, distant inflow feeding accretion or the gravitational  redshift from a ring of matter close to the SMBH ?
