GCNC 5285). Further analysis from the data of the night shows an object with R ~ 20.2 mag at coordinates R.A.= 23:48:19.00, Dec. = -17:54:17.0 (J2000) with estimated uncertanity of 0.7 arcsec is present on the frames and not visible on the DSS2 comparison images. Futher analysis are ongoing in order to check for variability and confirm its relationship to GRB 060707.
