GRB 220701A: Swift/UVOT Upper Limits

oates (***INSTITUTION***) and P. A. Evans (U. Leicester)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 220701A
175 s after the BAT trigger (Evans et al., GCN Circ. 32306).
No optical afterglow consistent with the XRT position
(Evans et al. GCN Circ. 32308)
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) = 0.008 in the direction of the burst
(Schlegel et al. 1998).
