GRB 190627A: Swift/UVOT Upper Limits

***UBS*** (***INSTITUTION***) and E. Sonbas (Adiyaman Univ.)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 190627A
114 s after the BAT trigger (Sonbas et al., GCN Circ. 24888).
No optical afterglow consistent with the uvot position
*** POSITION REFERENCE is GCN_Circ_24889 ***
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 initial exposures are:

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

white              114          144           29         >17.2
w1                3920         5555          393         >18.0
m2                3714         3914          197         >20.1
w2                4741         4941          197         >18.8

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.18 in the direction of the burst
(Schlegel et al. 1998).

GRB 190627A: Swift/UVOT Detection

***UBS*** (***INSTITUTION***) and E. Sonbas (Adiyaman Univ.)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 190627A
114 s after the BAT trigger (Sonbas et al., GCN Circ. 24888).
A source consistent with the uvot position
*** POSITION REFERENCE is GCN_Circ_24889 ***
is detected in the initial UVOT exposures.

The preliminary UVOT position is:
    RA  (J2000) =  16:19:18.69 = 244.82788 (deg.)
    Dec (J2000) = -05:17:20.8  =  -5.28912 (deg.)
with an estimated uncertainty of 0.46 arc sec. (radius, 90% confidence).

Preliminary detections and 3-sigma upper limits 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              114          144           29         17.43 +/- 0.07
w1                3920         4119          197         18.11 +/- 0.14
m2                3714         3914          197        >20.1
w2                4741         4941          197         19.55 +/- 0.32
