Berger (Harvard) reports on behalf of a larger collaboration:\n\n\"We observed the field of the short GRB 101219A (GCN 11467) with ACIS-S on\nthe Chandra X-ray Observatory starting on 2010 December 23.05 UT (3.942\ndays after the burst) for a total of 19.8 ksec.  We do not detect any\nsource within the XRT error circle (GCN 11461), or in coincidence with the\nproposed host galaxy (GCNs 11464, 11468, 11469).  We place a limit of about\n3e-15 erg/cm^2/s (3-sigma) on the flux of the X-ray afterglow at a mean time\nof 351.6 ksec after the burst, indicating a decline rate of alpha_X<-1.1.\n\nWe thank Harvey Tananbaum and the CXO scheduling staff (in particular Ping\nZhao) for rapidly approving and executing this observation.\"\n\n[GCN OPS NOTE(23dec10):  Per author's request, the \"3.942 hours\" was changed\nto \"3.942 days\".]",
