TITLE: GCN CIRCULAR NUMBER: 17020 SUBJECT: GRB 141102A found in ground analysis of BAT data DATE: 14/11/02 21:48:26 GMT FROM: Jay R. Cummings at NASA/GSFC/Swift J. R. Cummings on behalf of the Swift science team: A possibly short burst occurred at 12:51:40 UT (BAT trigger 617313). No source was found onboard. Ground analysis shows a significant source at RA, Dec 208.614, -47.100 which is: RA (J2000) 13h 54m 27.4s Dec (J2000) -47d 06' 00" with an estimated uncertainty of 4 arcmin radius, 90% containment. There were multiple peaks, at about T-0.2, T+0.4, T+1.7, and T+2.3. The latter two were stronger than the first two and resembled them in shape, the third was the largest. T90 is estimated as 2.5 +- 0.4 sec. The spectrum from T-0.3 to T+2.7 seconds is best fit by a simple powerlaw function with a photon index of 1.3 +- 0.5. The fluence was 3.7 x 10 ^-7 ergs/cm^2. A Swift TOO is not possible because the source is too close to the Sun for the next 39 days.
