GRB 120830A: Swift/UVOT Upper Limits

M. H. Siegel (PSU) and W. H. Baumgartner (***BA INSTITUTION***)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 120830A
59804 s after the LAT/IPN trigger (***Author*** et al., GCN Circ. ????).
No optical afterglow consistent with the uvot position
*** POSITION REFERENCE is uvotdetect ***
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            59804        67311         3679         >20.3

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.032 in the direction of the burst
(Schlegel et al. 1998).

GRB 120830A: Swift/UVOT Detection

M. H. Siegel (PSU) and W. H. Baumgartner (***BA INSTITUTION***)
report on behalf of the Swift/UVOT team:

The Swift/UVOT began settled observations of the field of GRB 120830A
59804 s after the LAT/IPN trigger (***Author*** et al., GCN Circ. ????).
A source consistent with the uvot position
*** POSITION REFERENCE is uvotdetect ***
is detected in the initial UVOT exposures.

The preliminary UVOT position is:
    RA  (J2000) =  05:54:00.65 =  88.50270 (deg.)
    Dec (J2000) = -28:42:06.4  = -28.70178 (deg.)
with an estimated uncertainty of 0.55 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            59804        59998          191         20.46 +/- 0.14

The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.032 in the direction of the burst
(Schlegel et al. 1998).
