Bloom (UC-Berkeley) report on behalf of a larger\ncollaboration:\n\nWe re-analyzed our GMOS imaging data on GRB070429B (Cucchiara et al.,\nGCN 6368).  We found the position previously reported for the sole\nobject in the XRT error circle was incorrect.  An updated position for\nthis object is:\n\n\tRA = 21:52:03.729  (J2000)\n\tDEC = -38:49:42.84  (J2000)\n\nThis represents an offset of 2.70\" W and 0.05\" S from our previously\nreported location.  The new position was calculated with respect to\nseveral USNO-B1 objects in the field.  We estimate a positional\nuncertainty of 0.3\" in each coordinate.  \n\nWe apologize for any inconvenience this may have caused."
