Vanden Berk (PSU) report on behalf of the Swift Team:\n\nFollowing up the report of the Swift GRB (Campana, et al., GCN 5162),\nwe note that the BAT lightcurve shows a well separated second period\nof emission starting at ~T+220 sec and lasting until ~T+270 sec. \nThe shape of the emission is FRED-like.  Based on the 4-band TDRSS\nlightcurve, this second emission is significantly softer that the \noriginal emission at T+0. \n\nBased on initial data we find a refined XRT position of \nRA(J2000): 15 31 18.27, DEC(J2000): +00 17 07.6, with an error \nradius of 4.3 arcsec (90% confidence) and 3 arcsec from the previously \nreported UVOT candidate position. The XRT light curve shows a sharp \nincrease in the count rate starting around T+220 s from burst trigger, \napproximately coincident with the second BAT peak. \n\nAs shown in the table below, UVOT sees a fading afterglow in \nthe four finding chart exposures for this burst. In the table,\nT is the time in seconds since the BAT trigger at the start \nof the exposure. \n\n  T  Exposure Filter  Magnitude\n  83  100     White    17.6\n 188  400     V        17.2\n 866  400     V        17.8\n1274  100     White    18.4\n\nWe note that the location of this burst is ~11.3 hours from the Sun\nand therefore well suited for ground-based follow-ups. \nThere is no bright galaxy at this location in the archived SDSS images. \nWe will start receiving the full downlinked data set around 18:00 UT.",
