GRB 220118A: Swift/UVOT Upper Limits

Bellees (***INSTITUTION***) and Klingler (GSFC/UMBC/CRESSTII)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 220118A
99 s after the BAT trigger (Klingler et al., GCN Circ. 31490).
No optical afterglow consistent with the XRT position
*** POSITION REFERENCE is GCN_Notice ***
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

white_FC            99          249          147         >17.8
white               99          249          147         >17.8
u                  257          436          176         >17.3

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.025 in the direction of the burst
(Schlegel et al. 1998).

GRB 220118A: Swift/UVOT Detection

Bellees (***INSTITUTION***) and Klingler (GSFC/UMBC/CRESSTII)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 220118A
99 s after the BAT trigger (Klingler et al., GCN Circ. 31490).
A source consistent with the XRT position
*** POSITION REFERENCE is GCN_Notice ***
is detected in the initial UVOT exposures.

The preliminary UVOT position is:
    RA  (J2000) =  12:49:04.52 = 192.26885 (deg.)
    Dec (J2000) = +22:54:56.2  =  22.91562 (deg.)
with an estimated uncertainty of 0.44 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

white               99          249          147         17.93 +/- 0.05
u                  257          436          176         17.53 +/- 0.09

The magnitudes in the table are not corrected for the Galactic extinction
