(i.e. the Swift-BAT team):
Automated BAT ground analysis found a burst that occurred at 16:20:09 UT
with a significance of 9.1 sigma (15-200 keV) from the failed event data
of trigger #511739. The event is temporally coincident with the Fermi GBM
348250807. The best BAT location is RA, Dec = 317.9043, +57.0358 deg, which is
RA(J2000) = 21h 11m 37.03s
Dec(J2000) = +57d 02' 08.9"
with an uncertainty of 2.3 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 18%.
The mask-weighted light curve created from the failed event data
(available from 16:20:06 to 16:20:16 UT) shows a constant positive
rate from the beginning. And then, the rate increases by three times
around 16:20:13 UT. From the BAT raw light curve, the duration of
the event is ~35 sec long.
The spectrum extracted using the full event data is best fit by a simple
power-law model. The power law index of the spectrum is 1.4 +- 0.3
(90% confidence).
Since the GRB is too close to the Sun, no Swift ToO has been requested.
