GRB 110213B: Swift/UVOT Upper Limits

***UBS*** (***INSTITUTION***) and ***BA*** (***BA INSTITUTION***)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 110213B
***???*** s after the BAT trigger (***BA*** et al., GCN Circ. ????).
No optical afterglow consistent with the MAXI position
*** POSITION REFERENCE is GCN_Circ_11720 ***
is detected in the initial UVOT exposures.
Preliminary 3-sigma upper limits using the UVOT photometric system
(Poole et al. 2008, MNRAS, 383, 627) for the initial exposures are:

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

white        319348753    319349569          803         >21.3
v            319349576    319349925          344         >19.3
u            319347930    319348746          803         >20.0

The values quoted above are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.04 in the direction of the burst
(Schlegel et al. 1998).
