GCN Circular 13395

A. de Ugarte Postigo (IAA-CSIC, DARK/NBI), P. D'Avanzo (OaB/INAF), 
S. Campana (OaB/INAF), J. Gorosabel (IAA-CSIC), S. Covino (OaB/INAF), 
J.P.U. Fynbo (DARK/NBI), and C.C. Thoene (IAA-CSIC) report on behalf of 
a larger collaboration,

In light of the recent XRT observation (Littlejohns et al., GCN13394
Not found
 
 
) we 
have performed further analysis of the HAWKI data reported by D'Avanzo 
et al. (GCN 13391
Not found
 
 
). Within the error circle of the XRT source  we detect a 
point-like source and a galaxy at the following coordinates (J2000 +/- 0.3"):

Galaxy 1A (RA, Dec): 11:23:32.08, +08:55:44.7
Point-like 1B (RA, Dec): 11:23:32.30, +08:55:42.5

We have performed image subtraction between our two K-band observations 
and we detect no variability of any of these sources between the two epochs.

We also note that the galaxy is well detected in the SDSS with r=21.46 and a 
has a photometric redshift of 0.57+/-0.07.

Our observations also cover the second XRT source that lies slightly outside 
the BAT error circle. Within this region we detect 2 extended sources, with 
coordinates (J2000 +/- 0.3"):

Galaxy 2 (RA, Dec): 11:23:28.17, +08:55:57.6
Galaxy 3 (RA, Dec): 11:23:28.07, +08:55:56.8

Again, no variability is found within the second XRT position. These are detected 
as a single source in SDSS at r=21.55 and a photometric redshift of 0.43+/-0.07.
