Zhang (PSU) report on behalf of\nthe Swift Team:\n\nAt 19:05:44 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated emission from the location of the flare star CC Eri (trigger=516027). \nSwift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA, Dec 38.526, -43.825 which is \n  RA(J2000) = 02h 34m 06s\n  Dec(J2000) = -43d 49' 30\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  As is usual for a 5-minute image trigger\nthere is no obvious variation in the immediately available lightcurve. \n\nThe XRT began observing the field at 19:12:21.5 UT, 397.5 seconds after\nthe BAT trigger. XRT found a bright X-ray source located at RA, Dec\n38.5956, -43.7978 which is equivalent to:\n  RA(J2000)  = +02h 34m 22.94s\n  Dec(J2000) = -43d 47' 52.1\"\nwith an uncertainty of 4.8 arcseconds (radius, 90% containment). This\nlocation is 205 arcseconds from the BAT onboard position. This position\nis 5.4 arcseconds from that of a known X-ray source: the flare star, CC Eri. \nNo event data are yet available to determine the column density using X-ray\nspectroscopy. \n\nThe initial flux in the 2.5 s image was 7.03e-09 erg cm^-2 s^-1 (0.2-10\nkeV). \n\nUVOT took a finding chart exposure of 27 seconds with the White filter\nstarting 406 seconds after the BAT trigger. This source is very\nbright, as expected for a flaring star with a quiescent magnitude\nof V=8.8. More analysis will be required to provide an estimate of the\nmagnitude. The expected extinction corresponds to an E(B-V) of 0.02.",
