SUBJECT: GRB 051114: Swift-BAT detection of a short burst

on behalf of the Swift-BAT team:

At 04:11:30 UT, Swift-BAT triggered and located GRB 051114 (trigger=163844).
The on-board software did not locate this burst with sufficient significance,
however ground processing was able to extract a location.  The BAT ground
calculated location is RA,Dec 226.274d,+60.150d {15h 05m 06s,+60d 09' 00"}
(J2000), with an uncertainty of 3 arcmin (radius, 90% containment, stat+sys).
The BAT light curve shows two short peaks separated by ~1 sec with a total
duration of 2 sec.  The peak count rate was ~1500 counts/sec (15-350 keV),
at ~0.5 seconds after the trigger.

We note that due a handling mistake on the ground, the GCN BAT_POSITION Notice
was generated with incorrect values in the following fields:  TRIGGER_NUM,
GRB_INTEN, BKG_INTEN, BKG_TIME, BKG_DUR, GRB_TIME, MERIT_PARAMS.  All the 
other numbers in the Notice are correct (including the Sun & Moon locations 
and the Galactic and Ecliptic coordinates).

on behalf of the Swift-BAT team:

Using the full data set from T-4 to T+16 sec (all the data we will
get on this ground-detected burst), we report further analysis
of BAT GRB 051114 (trigger #163844) (Cummings, et al., GCN 4272). 
The BAT ground-calculated position is (RA,Dec) = 226.266d,+60.156d
{15h 05m 04s,60d 09' 22"} [deg; J2000] +- 2 arcmin, (radius,
sys+stat, 90% containment).  The partial coding was 78%. 

The light curve shows two peaks of roughly equal intensity, the 
second slightly softer, one from T+0.2 to T+0.9 sec and one from 
T+1.3 to T+2.7 sec.  T90 (15-350 keV) is (2.2 +- 0.3) sec (estimated 
error including systematics). 

The power law index of the time-averaged spectrum is 1.22 +- 0.27. 
The fluence in the 15-150 keV band is (1.32 +- 0.24) x 10^-7 erg/cm2. 
The 1-sec peak photon flux measured from T+0.2 sec in the 15-150 keV
band is (0.73 +- 0.16) ph/cm2/sec.  All the quoted errors are at the
90% confidence level.

Dale A. Frail (NRAO) reports on behalf of a larger collaboration:

"We observed the field of the burst GRB 051114 (GCN 4272; GCN 4275)
with the Very Large Array at 8.5 GHz around November 15.58 UT. Within
the 2-arcmin radius of the BAT position (GCN 4275) we find no radio
emission above 4-sigma, for an rms noise of 50 microJy.

The National Radio Astronomy Observatory is a facility of the National
Science Foundation operated under cooperative agreement by Associated
Universities, Inc."

The Swift-XRT started a 13.6 ks ToO observation of the
field of GRB051114 (Cummings at al., GCN 4272) on
November 15 at 15:18:23 UT, 35 hours after the burst 
trigger.
No new source was detected within the BAT refined error
circle (Sakamoto at al., GCN 4275) down to a limiting flux
of 2.3e-14 ergs/cm/cm/s.
