GRB 101204A: Swift/UVOT Upper Limits

***UBS*** (***INSTITUTION***) and Cummings (GSFC/UMBC/CRESST)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 101204A
126195 s after the BAT trigger (Cummings et al., GCN Circ. 11440).
No optical afterglow consistent with the uvot position
*** POSITION REFERENCE is GCN_Circ_11442 ***
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

v               126195       133279         2563         >20.0
u               127505       134378         2329         >19.7

The values quoted above are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.03 in the direction of the burst
(Schlegel et al. 1998).
