Sollerman (DARK Cosmology Centre, Niels Bohr Institute) report:\n\nWe have performed PSF-matched image subtraction on the images acquired\nby Jensen et al. (GCN #3589).  The images were obtained from the Danish\n1.54m+DFOSC at La Silla on 2005 July 11.3 and 12.3 UT.\n\nPSF-matched image subtraction using the Pan-STARRS Optimal Image\nSubtraction (POI Sub) code reveals a residual, in the sense that the\nsource fades between the first and the second epochs.  The position of\nthe variable source corresponds to the source identified by Jensen et\nal. (GCN #3589) on the edge of a nearby galaxy (z=0.16; Price, Roth &\nFox, GCN #3605) as consistent with the Chandra source (Fox et al., GCN\n#3585).  This detection of optical variability increases the likelihood\nthat this source is the afterglow of the short/hard GRB 050709.\n\nA figure showing the subtraction is available at\nhttp://www.ifa.hawaii.edu/~price/grb050709candidate.jpg\n\nThis message may be cited.",
