TITLE: GCN CIRCULAR
NUMBER: 26327
SUBJECT: GRB 191130A, a long burst detected in Swift-BAT ground analysis
DATE: 19/12/03 15:22:09 GMT

At 13:05:02 UT on 2019-11-30, GRB 191130A occurred during a
preplanned slew of the Neil Gehrels Swift Observatory and was
later found in the Swift/BAT ground analysis.
Using the data set from T-139 to T+106 sec from the recent telemetry
downlink (observation ID: 03110538005),
the BAT ground-calculated position is
RA, Dec = 133.137, 5.017 deg which is
RA(J2000) = 08h 52m 32.9s
Dec(J2000) = +05d 01' 02.1"
with an uncertainty of 1.7 arcmin, (radius, sys+stat, 90% containment).
The mask-weighted light curve shows a single-pulse structure that starts
at ~T0, peaks at ~T+7 s, and ends at ~T+22 s. T90 (15-350 keV)
is 17.6 +- 2.9 sec (estimated error including systematics).
The time-averaged spectrum from T-0.0 to T+22.1 sec is best fit by a simple
power-law model. The power law index of the time-averaged spectrum is
1.95 +- 0.13. The fluence in the 15-150 keV band is 6.86 +- 0.6 x 10^-7
erg/cm2.
The 1-sec peak photon flux measured from T+6.18 sec in the 15-150 keV band
is 1.1 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence
level.

SUBJECT: GRB 191130A: Swift ToO observations
DATE: 19/12/04 08:16:15 GMT
FROM: Phil Evans at U of Leicester
P. A. Evans (U. Leicester) reports on behalf of the Swift team:
Swift has initiated a ToO observation of the Swift/BAT GRB 191130A.
Automated analysis of the XRT data will be presented online at
https://www.swift.ac.uk/ToO_GRBs/00020950
Any uncatalogued X-ray sources detected in this analysis will be
reported on this website and via GCN COUNTERPART notices. These are
not necessarily related to the Swift/BAT event. Any X-ray source
considered to be a probable afterglow candidate will be reported via a
GCN Circular after manual consideration.
Details of the XRT automated analysis methods are detailed in Evans et
al. (2007, A&A, 469, 379; 2009, MNRAS, 397, 1177 and 2014, ApJS, 210, 8).

FROM: Boris Sbarufatti at PSU
B. Sbarufatti (PSU) ), J. D. Gropp (PSU) and P.A. Evans (U. Leicester)
report on behalf of the Swift-XRT team:
Swift-XRT has performed follow-up observations of the
Swift/BAT-detected burst GRB 191130A (Palmer et al. GCN Circ. 26327),
collecting 5.0 ks of Photon Counting (PC) mode data between T0+310.0 ks
and T0+343.5 ks.
Three uncatalogued sources were detected, all of them too far from the
GRB position to be likely afterglow candidates.
The 3-sigma upper limit at the BAT position is 1.19e-3 ct s^-1,
corresponding to a 0.3-10 keV observed flux of 6.0e-14 erg cm^-2 s^-1
(assuming a typical GRB spectrum).
The results of the XRT-team automatic analysis of the XRT observations,
including a position-specific upper limit calculator, are available at
https://www.swift.ac.uk/ToO_GRBs/00020950.
