GRB 181110A: Swift/UVOT Upper Limits

N. P. M. Kuin (UCL-MSSL) 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 181110A
72 s after the BAT trigger (Evans et al., GCN Circ. 23413).
No optical afterglow consistent with the XRT position
(Goad et al. GCN Circ. 23417)
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:

GRB 181110A: Swift/UVOT Detection

N. P. M. Kuin (UCL-MSSL) 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 181110A
72 s after the BAT trigger (Evans et al., GCN Circ. 23413).
A source consistent with the XRT position
(Goad et al. GCN Circ. 23417)
is detected in the initial UVOT exposures.

The preliminary UVOT position is:
    RA  (J2000) =  20:09:16.27 = 302.31781 (deg.)
    Dec (J2000) = -36:53:47.9  = -36.89664 (deg.)
with an estimated uncertainty of 0.46 arc sec. (radius, 90% confidence).

Preliminary detections using the UVOT photometric system
(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are: 

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