We present Giant Metrewave Radio Telescope (GMRT) HI 21cm emission images ofthe z=0.009 damped Lyman-alpha (DLA) absorber towards the QSO HS 1543+5921. TheDLA has been earlier identified as a low surface brightness galaxy SBS 1543+593at an impact parameter of ~ 400 pc to the QSO line of sight. The extremely lowredshift of the absorber allows us to make spatially resolved images of the21cm emission; besides the HI mass, this also enables us to determine thevelocity field of the galaxy and, hence, to estimate its dynamical mass.  We obtain a total HI mass of ~ 1.4x10^9 Msun, considerably smaller than thevalue of M*(HI) determined from blind 21cm emission surveys. This continues thetrend of low HI mass in all low redshift DLAs for which HI emissionobservations have been attempted. We also find that the QSO lies behind aregion of low local HI column density in the foreground galaxy. This isinteresting in view of suggestions that DLA samples are biased against high HIcolumn density systems. The dynamical mass of the galaxy is found to be Mdyn ~5x10^9 Msun.Comment: Accepted for publication in A&
