GRB 241115A: Swift/UVOT Upper Limits

S.P.R. Shilling (Lancaster) and M. Williams (PSU)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 241115A
114 s after the BAT trigger (Williams et al., GCN Circ. 38235).
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 first
finding chart (FC) exposure and subsequent exposures are:

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

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 1.028 in the direction of the burst
(Schlegel et al. 1998).
