GRB 190114C: Swift/UVOT Upper Limits

M. H. Siegel (PSU) and J. D. Gropp (PSU)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 190114C
74 s after the BAT trigger (Gropp et al., GCN Circ. 23688).
No optical afterglow consistent with the XRT position
(Osborne et al. GCN Circ. 23704)
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            74          223          147         >14.9
u_FC               286          535          246         >17.5
white               74          223          147         >14.9
u                  286          535          246         >17.5

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.01 in the direction of the burst
(Schlegel et al. 1998).

GRB 190114C: Swift/UVOT Detection

M. H. Siegel (PSU) and J. D. Gropp (PSU)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 190114C
74 s after the BAT trigger (Gropp et al., GCN Circ. 23688).
A source consistent with the XRT position
(Osborne et al. GCN Circ. 23704)
is detected in the initial UVOT exposures.

The preliminary UVOT position is:
    RA  (J2000) =  03:38:01.16 =  54.50484 (deg.)
    Dec (J2000) = -26:56:46.9  = -26.94637 (deg.)
with an estimated uncertainty of 0.42 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               74          223          147         14.90 +/- 0.02
u                  286          535          246         17.62 +/- 0.06

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.01 in the direction of the burst
(Schlegel et al. 1998).
