TITLE: GCN CIRCULAR
NUMBER: 15483
SUBJECT: GRB 131110A found in ground analysis of BAT slew event data
DATE: 13/11/14 04:11:17 GMT
FROM: Jay R. Cummings at NASA/GSFC/Swift
J. R. Cummings and D. M Palmer report on behalf of the Swift-BAT science team:
At 11:53:11 Swift was slewing. A rate increase during the slew was noticed in
ground post-processing. The BAT lightcurve shows a slow rise and decay peak
with about 90 seconds duration. A mosaic of BAT images from the slew shows
a significant source at RA, Dec 69.264, -17.258 which is
RA (J2000) 04h 37m 3.4s
Dec (J2000) -17d 15' 30"
with an estimated error radius of 4 arcmin.
A Swift TOO has been requested.

We report further analysis of the ground-detected Swift-BAT slew GRB 131110A
(Cummings and Palmer, GCN circ # 15483). The best BAT position is
RA, Dec 69.268, -17.259 which is
RA (J2000) 04h 37m 4.4s
Dec (J2000) -17d 15' 34"
with an estimated 90% containment radius of 0.8 arcmin.
The BAT mask-weighted lightcurve shows a single broad peak with a slow rise to a
plateau at T+25 seconds, lasting about 70 seconds, and a slow decay. T90 is about
100 +- 10 seconds.
The average spectrum from T0 to T+90 (after which the source had a low mask coding
factor in BAT) is best fit by a simple power law function with a photon index of
1.61 +- 0.09. The fluence from 15-150 keV during this interval was
(3.53 +- 0.10) x 10^-6 ergs/cm^2/sec. Errors are 90% confidence.
A Swift TOO has been approved with the observation number 20327, to be performed
11/15/2013.

SUBJECT: GRB 131110A: Swift-XRT and UVOT upper limits
DATE: 13/11/15 15:29:45 GMT
FROM: Kim Page at U.of Leicester
K.L. Page, P.A. Evans (U. Leicester) and N.P.M. Kuin (UCL-MSSL) report on
behalf of the Swift-XRT and UVOT teams:
The Swift-XRT began observing the field of GRB 131011A 397 ks after the
event (Cummings & Palmer, GCN Circ. 15483). In 2.8 ks of Photon Counting
(PC) mode data, no source was found in the BAT error circle; the 3-sigma
upper limit (0.3-10 keV) is 3.6e-3 count s^-1
The Swift-UVOT also began observations of the field of GRB 131110Aat the
same time. No optical afterglow was found in the image. Preliminary
3-sigma upper limits using the UVOT photometric system (Breeveld et al.
2011, AIP Conf. Proc. 1358, 373) for the initial exposures are:
Filter T_start(s) T_stop(s) Exp(s) Mag
white 397556 409058 892 >20.2
v 398095 409489 938 >18.6
u 397018 408678 892 >19.2
