  "body": "GRB 060712: Swift/UVOT Upper Limits\n\nS. T. Holland (GSFC/USRA) reports on behalf of the Swift/UVOT team:\n\nThe Swift UVOT began taking data on the field of GRB 060712 (Swift\nTrigger 218582) 4983 s after the BAT trigger (Cummings et al. 2006,\nGCN Circular 5301).  UVOT was in an engineering mode when the burst\noccurred so it did not make prompt observations of the field of this\nburst.  No new source, relative to the DSS, is seen in any of the UVOT\nexposures inside the XRT error circle (Vetere et al. 2006, GCN\nCircular 5305).  The 3-sigma upper limits are:\n\n         Midpoint   Exposure\nFilter  Time (s)     (s)       Mag\n    V      5141       197      19.44  3-sigma upper limit\n    B      5959       197      20.64  3-sigma upper limit\n    U      5754       197      20.06  3-sigma upper limit\nUVW1     5550       197      20.16  3-sigma upper limit\nUVM2     5345       197      19.38  3-sigma upper limit\nWhite     4985        98      19.88  3-sigma upper limit (160-650 nm)\n\nThese upper limits have not been corrected for the estimated Galactic\nreddening of E_{B-V} = 0.01 mag (Schlegel et al. 1998).\n\n/\n\\\n/",
