GRB 200713A: Swift/UVOT Upper Limits

Baer (***INSTITUTION***) and A. Y. Lien (GSFC/UMBC)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 200713A
159 s after the BAT trigger (Lien et al., GCN Circ. 28088).
No optical afterglow consistent with the XRT position
(Evans et al. GCN Circ. 28089)
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:

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

white_FC           159          309          147         >20.6
white              159          309          147         >20.6
u                  317          497          177         >19.6

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).
