GRB 220527A: Swift/UVOT Upper Limits

S. J. LaPorte (PSU) and A. P. Beardmore (***BA INSTITUTION***)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 220527A
30123 s after the LAT trigger (***Author*** et al., GCN Circ. ????).
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 initial exposures are:

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

u                30123        42493         4890         >18.1

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.074 in the direction of the burst
(Schlegel et al. 1998).

GRB 220527A: Swift/UVOT Detection

S. J. LaPorte (PSU) and A. P. Beardmore (***BA INSTITUTION***)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 220527A
30123 s after the LAT trigger (***Author*** et al., GCN Circ. ????).
A source consistent with the XRT position
*** POSITION REFERENCE is GRB_Auto_Processing ***
is detected in the initial UVOT exposures.

The preliminary UVOT position is:
    RA  (J2000) =  21:34:06.73 = 323.52804 (deg.)
    Dec (J2000) = -14:58:18.1  = -14.97169 (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

u                30123        31856         1706         18.00 +/- 0.04

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