GRB 251014: Swift/UVOT Upper Limits

***UBS*** (***INSTITUTION***) and N. J. Klingler (GSFC/UMBC/CRESSTII)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 251014
160 s after the BAT trigger (Klingler et al., GCN Circ. 42274).
No optical afterglow consistent with the BAT position
*** POSITION REFERENCE is GCN_FOM_Notice ***
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 first
finding chart (FC) exposure and subsequent exposures are:

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.020 in the direction of the burst
(Schlegel et al. 1998).
