NUMBER: 12599

At 18:57:42 UTC, on November 26, 2011, BAT count rates spiked during
a pre-planned slew maneuver. In a mosaic of images from slew event data,
a significant source was found at RA, Dec 276.057, +51.461, which is
RA (J2000) 18h 24m 13.6s
Dec (J2000) 51d 27' 38"
with an estimated uncertainty of 3 arcmin radius. This location is
currently about 29 degrees from the Sun. No Swift followup is anticipated.
It was a short, hard GRB with multiple peaks. T90 was 0.8 +/- 0.1 seconds.
The BAT spectrum is best fit by a simple powerlaw with a photon index of
1.1 +/- 0.3. The fluence in 0.8 seconds was 7 +/- 2 ergs/cm^2. The peak
flux was 1.2 +/- 0.4 photons/cm^2/s. The uncertainties are 90% estimated
including systematics.

The magnitude of the fluence was omitted in the circular, it should
have been (7 +/- 2) x 10^-8 ergs/cm^2. We thank Kevin Hurley for
pointing out the error.
