GCN Circular 12309
D. Xu reports on behalf of a larger collaboration: We inspected the archival datasets of the XRT field (Zhang & Grupe, GCN 12308) of GRB 110825A (Hurley et al., GCN 12307). We found an extended (in the SE-NW direction) object centered at RA (J2000): 02:59:11.966 Dec(J2000): +15:25:41.34 which is 5.7 arcsec to the center of the XRT error circle with a radius of 3.9 arcsec (90% confidence; GCN 12308). Therefore, if the XRT source is really the counterpart of IPN-triangulated GRB110825A or even of a new burst (as the XRT position is outside the IPN error box), the extended object could be the host galaxy of this event. Inspection of the archives reveals the extended object: (1) being U1050_00797295 (USNO at ESO) with r=18.4 mag and b=19.2 mag; (2) being 02591193+1525410 (2MASS at CADC) with J=16.493+/-0.140 mag, H=15.810+/-0.134 mag, and K=15.210+/-0.149 mag; and (3) being 1054-0031516 (USNO B1 at CDS) with R1=18.91 mag and B1=19.84 mag. In addition, preliminary UVOT photometry (standard 5arcsec aperture photometry) centered on the above location reveals v(AB)>19.28 u(AB)>21.90 wh(AB)=21.55 +/- 0.21 More accurate UVOT photometry is required as the OT is extended and relatively faint for the UVOT telescope. Considering the above possible host galaxy is brighter than usual GRB hosts, this source might be a low-redshift one.
