TITLE: GCN CIRCULAR NUMBER: 11483 SUBJECT: GRB 101219A: Chandra Observations DATE: 10/12/23 22:13:13 GMT FROM: Edo Berger at Harvard E. Berger (Harvard) reports on behalf of a larger collaboration: "We observed the field of the short GRB 101219A (GCN 11467) with ACIS-S on the Chandra X-ray Observatory starting on 2010 December 23.05 UT (3.942 days after the burst) for a total of 19.8 ksec. We do not detect any source within the XRT error circle (GCN 11461), or in coincidence with the proposed host galaxy (GCNs 11464, 11468, 11469). We place a limit of about 3e-15 erg/cm^2/s (3-sigma) on the flux of the X-ray afterglow at a mean time of 351.6 ksec after the burst, indicating a decline rate of alpha_X<-1.1. We thank Harvey Tananbaum and the CXO scheduling staff (in particular Ping Zhao) for rapidly approving and executing this observation."
