GRB 140808A: Swift/UVOT Upper Limits

S. R. Oates (IAA-CSIC/UCL-MSSL) and S. B. Cenko (***BA INSTITUTION***)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 140808A
560248 s after the GBM trigger (***Author*** et al., GCN Circ. ????).
No optical afterglow consistent with the optical position
(Singer et al. GCN Circ. 16668)
is detected in the initial UVOT exposures.
Preliminary 3-sigma upper limits using the UVOT photometric system
(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the initial exposures are:

Filter         T_start(s)   T_stop(s)      Exp(s)         Mag

white           560351       565512          835         >22.3
v               560455       566302          857         >20.4
u               560248       570360         1212         >21.7

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.02 in the direction of the burst
(Schlegel et al. 1998).
