W. Landsman (GSFC/Adnet) and T. Sakamoto (GSFC/UMBC) report on behalf of
the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 101114A
20.3 hrs after the BAT trigger (Sakamoto et al., GCN 11405). We do not
detect any source at the enhanced Swift XRT position (Evans GCN 11406,
11415). 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 74084 86413 2325 > 21.9
v 74901 87330 2567 > 20.5
u 73267 91074 2822 > 21.0
The quoted upper limits have not been corrected for the expected
Galactic extinction along the line of sight of E_(B-V) = 0.19 (Schlegel
et al. 1998). All photometry is on the UVOT photometric system
described in Poole et al. (2008, MNRAS, 383, 627).
