White (GSFC)\non behalf of the Swift-BAT team:\n\nAt 03:33:12 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated on-board GRB 050306.  The burst location is 19 deg from the Moon,\nand because of the Moon constraint, the spacecraft did not slew\nto the burst location.\n\nUsing the time interval of the burst, the ground-calculated location\nis RA,Dec 282.337,-9.162 (J2000) with an uncertainty of 3 arcmin\n(radius, including a systematic uncertainty, 90% containment).\nThe burst was 51 degrees off the BAT boresight (19% encoding).\n\nThe burst lightcurve has 2 main peaks.  At this time we have access\nonly to the TDRSS lightcuve which terminates at T+180 sec.  The lightcurve \nstarts to rise again at T+165 sec indicating a possible 3rd peak.\nThe peak count rate is 2.4 counts/cm2/sec.",
