Starling (U Leicester) and E. Troja (INAF-IASFPA) report on\nbehalf of the Swift Team:\n\nBeginning at 14:45:42 UT, the Swift Burst Alert Telescope (BAT) \ntriggered and located a point source in a 27 minute image. \nSwift slewed immediately to the source at the location of the \nknown gamma-ray transient IGR J08408-4503 (ATel 813; Gotz et al.)\n= V* LM Vel (ATel 818; Kennea et al.). The BAT\non-board calculated  location is  RA,Dec 130.214, -45.063 \n{08h 40m 51s, -45d 03' 44\"} (J2000) with an uncertainty of 3 arcmin \n(radius, 90% containment, including  systematic uncertainty). \nAs is typical for long image triggers, the BAT light curve \nshows no obvious variation attributable to the source. \n\nThe XRT began observing the field at 15:17:07 UT, 1885 seconds after the\nBAT trigger (which is at the beginning of the 27 minute discovery image). \nXRT found a bright X-ray source located at \nRA(J2000) = 08h 40m 47.3s, Dec(J2000) = -45d 03' 29.5\", with an\nestimated uncertainty of about 8 arcseconds (90% confidence radius,\nincluding boresight uncertainties).  This location is 46 arcseconds \nfrom the BAT on-board position, within the BAT error circle. \nIt is 5.2 arcseconds from the pulsating star V* LM Vel. \nThe initial flux in the 2.5s image was about 1e-9 erg/cm2/s (0.2-10 keV).  \nNo obvious variability is seen in the quick-look light curve. \n\nDue to the presence of bright stars in the field of view, the UVOT was unable to observe.",
