Leicester) \nreport on behalf of the Swift-XRT team.\n\nUsing 161 s of overlapping XRT Photon Counting mode and UVOT\ndata for GRB 080307, we find an astrometrically corrected X-ray\nposition (using the XRT-UVOT alignment and matching UVOT field sources\nto the USNO-B1 catalogue): RA, Dec = 136.62799, +35.13896 which is equivalent\nto:\n\nRA (J2000): 09h 06m 30.72s\nDec (J2000): +35d 08' 20.3\"\n\nwith an uncertainty of 1.8 arcsec (radius, 90% confidence).\n\nThis position may be improved as more data are received. The latest position\ncan be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is\ndescribed by Goad et al.
