GRB 060712: Swift/UVOT Upper Limits
S. T. Holland (GSFC/USRA) reports on behalf of the Swift/UVOT team:
The Swift UVOT began taking data on the field of GRB 060712 (Swift
Trigger 218582) 4983 s after the BAT trigger (Cummings et al. 2006,
GCN Circular 5301). UVOT was in an engineering mode when the burst
occurred so it did not make prompt observations of the field of this
burst. No new source, relative to the DSS, is seen in any of the UVOT
exposures inside the XRT error circle (Vetere et al. 2006, GCN
Circular 5305). The 3-sigma upper limits are:
Midpoint Exposure
Filter Time (s) (s) Mag
V 5141 197 19.44 3-sigma upper limit
B 5959 197 20.64 3-sigma upper limit
U 5754 197 20.06 3-sigma upper limit
UVW1 5550 197 20.16 3-sigma upper limit
UVM2 5345 197 19.38 3-sigma upper limit
White 4985 98 19.88 3-sigma upper limit (160-650 nm)
These upper limits have not been corrected for the estimated Galactic
reddening of E_{B-V} = 0.01 mag (Schlegel et al. 1998).
