Negoro \n(Nihon U.) report on behalf of the MAXI team:\n\nSwift observed the field of GRB 110213B (Negoro et al., GCN Circ. 11716) \ncentered at the refined MAXI/GSC position reported by Morii et al. \n(GCN Circ. 11720) for 2 ks from 2011-02-14T03:42:19 (T0+47 ks).\n\nWe find three point sources in the XRT field of view:\n\nSource          (R.A., Dec.)  J2000                         flux\n------   -----------------------------------------------   -------\n  A      (41.562 deg, +1.245 deg)= (02 46 15, +01 14 42)   0.008 c/s\n  B      (41.757 deg, +1.146 deg)= (02 47 02, +01 08 46)   0.029 c/s\n  C      (41.550 deg, +1.391 deg)= (02 46 12, +01 23 28)   0.003 c/s\n\nSource A is located 0.1' from 1RXS J024615.3+011427, a RASS source \nidentified to an AF star.\nSource C is located 0.1' from a quasar Q 0243+011.\nNo catalogued source was found for Source B.\n\nSource B, the brightest of the three, and found near the edge of the \nfield of view, is the most likely candidate for the afterglow of \nGRB 110213B.  Another Swift observation is planned to confirm its fading.\n\nWe thank the Swift operation team for performing a prompt TOO observation \nand making the data available quickly.",
