C. A. Swenson (PSU) and D. Kocevski (NASA/GSFC/ORAU) report
on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of
GRB 130606B 106.6 ks after the Fermi/LAT trigger (Vianello
et al., GCN 14795). No optical afterglow consistent with
the position of the potential X-ray candidate (Kennea, GCN
14820) is detected in the UVOT exposures. A preliminary 3-
sigma upper limit using the UVOT photometric system (Breveld
et al., 2011, AIP Conf. Proc. 1358, 373) for the initial
exposures is:
Filter T_start(s) T_stop(s) Exp(s) Mag

The magnitudes in the table are not corrected for the Galactic
extinction due to the reddening of E(B-V) = 0.10 in the
direction of the burst (Schlegel et al. 1998)
