Several images in R_c pass-band (300 sec each) were taken \nin two sessions starting at UT 21:11:10, 11-03-2012.\n\nIn the initial co-added R_c frame (3x300sec), we did not detect any \nnew optical source within the XRT error-box (Osborne et al., \nGCN Circ. 13042) down to a limiting magnitude of ~ 20.5 mag. \nThe photometry was done in comparison to nearby USNO- B1 stars.\n\nThis massage may be cited.",
