A. N. Morgan, M. M. Chester, and C. Pagani (PSU) report on
behalf of the Swift/UVOT team:
The Swift UVOT began taking data on the field of GRB 060728
121s after the BAT trigger (Pagani et al., GCN Circ 5360).
No new source, relative to the DSS, is seen inside the
refined BAT error circle (Palmer et al., GCN Circ 5363).
Images were not taken in all filters due to a bright source
in the field-of-view. The 3-sigma limiting magnitudes for
the first finding chart and the coadded images are listed
below.
Finding chart:
Filter Midpoint (s) Exposure (s) 3-sigma LM
V 319 393 19.3
Coadded images:
Filter T_range(s) EXPOSURE (s) 3-sigma LM
V 121-6586 1113 19.9
UVW1 551-10828 1553 21.2
UVM2 527-6690 765 20.9
UVW2 578-11225 1029 21.2
T_range is calculated from the time of the burst. These
upper limits have not been corrected for the estimated
Galactic reddening of E(B-V) = 0.012 mag (Schlegel et
al. 1998).
