The previously-reported observations covered 8\ngalaxies within the error region, listed below; the typical upper limit\nfrom these observations is 2.6e-13 erg cm^-2 s^-1 (0.3-10 keV).\nSubsequently a 37-point tiled observation has been performed, covering a\nportion of the LMC within the GW error region, centred on RA,Dec =\n103.8877, -68.3023 (06h 55m 33.04s, -68d 18' 08.3\"), with ~60 s exposure\nper tile. No X-ray sources were found in these observations. The upper\nlimits from these observations range from 3.3e-12 to 1.3e-11 erg cm^-2\ns^-1 (0.3-10 keV).\n\nThe galaxies covered by the original observations were:\nESO089-015\nESO089-016\nESO088-018\nESO088-017\nPGC298845\nESO126-002\nESO126-004\nESO089-009\nESO090-011\nPGC314417\n\nDetails of these observations have been uploaded to the GraceDB.\n\nThis circular is an official product of the Swift team.\n\n[GCN OPS NOTE(19sep15): This Circular was originally published on 14:01 19-Sep-2015 UT.]",
