GRB 190322: Swift/UVOT Upper Limits

J. D. Gropp (PSU) and ***BA*** (***BA INSTITUTION***)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 190322
873 s after the BAT trigger (***Author*** et al., GCN Circ. ????).
No optical afterglow consistent with the XRT position
*** POSITION REFERENCE is GRB_Auto_Processing ***
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                 1056         1447           72         >17.9
u                  873         1401          206         >19.3
w1                1104         5178          255         >19.1
m2                1080         4972          236         >19.4
w2                1032         1429           78         >19.4

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 1.37 in the direction of the burst
(Schlegel et al. 1998).
