E. A. Hoversten (PSU) and W. H. Baumgartner (GSFC/UMBC) report
on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB
100513A 130s after the BAT trigger (Baumgartner et al., GCN 10746).
We do not detect any source at the enhanced Swift XRT position
(Evans et al., GCN 10751) nor at the position of the PAIRITEL NIR
detection (Morgan et al., GCN 10747). UVOT magnitude 3-sigma
upper limits are reported in the following table:
Filter T_start T_stop Exp(s) Mag (3-sigma upper limit)
-------------------------------------------------------------
white 130 1707 411 > 21.29
v 618 1757 136 > 19.02
b 544 1683 116 > 19.89
u 289 1658 343 > 20.22
uvw1 667 1462 97 > 19.33
uvm2 5000 5200 196 > 19.59
uvw2 6026 6226 196 > 20.03
The quoted upper limits have not been corrected for the expected
Galactic extinction along the line of sight of E_(B-V) = 0.05 mag
(Schlegel et al. 1998). All photometry is on the UVOT photometric
system described in Poole et al. (2008, MNRAS, 383, 627).
