GRB 220714: Swift/UVOT Upper Limits

N. P. M. Kuin (UCL-MSSL) and S. L. Laha (GSFC/UMBC)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 220714
947 s after the BAT trigger (Laha et al., GCN Circ. 32391).
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 initial exposures are:

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

v                 1153         6325          235         >18.3

w2                1129         6119          236         >19.2

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.774 in the direction of the burst
(Schlegel et al. 1998).
