Stella (INAF, OARm), report:\n\nPhotometric analysis of our set of images of GRB 050714B (Levan et al., GCN 3613;\nTueller et al., GCN 3615) taken with the VLT-FORS1 in the R band\ndoes not confirm the proposed identification of the object reported by Malesani et al.\n(GCN 3614) as the candidate optical afterglow.\n\nThe object shows constant brightness between Jul 14.984 UT and Jul 15.040 UT\n(from 56 to 137 minutes after the GRB, respectively) at about R = 21.7,\ntaking as reference the USNO star U0675-11455984 with magnitude R = 15.3.\nA light curve for this object can be seen at the following URL:\n\n  http://www.sissa.it/~malesani/GRB/050714B/candidate_lc.gif\n\nWe give below the refined coordinates for the candidate,\nadopting an astrometric solution based on the 2MASS catalog:\n\n   alpha(J2000) = 11:18:47.71,  delta(J2000) = -15:32:51.6\n\nThe error is 0.2 arcsec.\n\nWe note that two fainter objects are present close to the edge of the XRT error circle\n\nA: alpha(J2000) = 11:18:47.71,  delta(J2000) = -15:33:00.9\nB: alpha(J2000) = 11:18:48.19,  delta(J2000) = -15:32:50.3\n\nNone of such objects is seen to vary by more than ~0.1 mag.\n\nA finding chart can be found here:\n\n  http://www.sissa.it/~malesani/GRB/050714B/GRB050714B_finder.jpg\n\nThis message may be cited.",
