SUBJECT: GRB 190728A: Fermi GBM Final Real-time Localization
DATE: 19/07/28 06:41:31 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely SHORT GRB
At 06:30:36 UT on 28 Jul 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190728A (trigger 585988241.852436 / 190728271).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 356.7, Dec = 5.4 (J2000 degrees, equivalent to J2000 23h 46m, 5d 24'), with a statistical uncertainty of 5.7 degrees.
The angle from the Fermi LAT boresight is 85.0 degrees.

SUBJECT: IPN triangulation of GRB 190728A (short)
DATE: 19/07/28 19:27:50 GMT
FROM: Dmitry Svinkin at Ioffe Institute
D. Svinkin and K. Hurley, on behalf of the IPN,
A. Goldstein, M. S. Briggs, and C. Wilson-Hodge
on behalf of the Fermi GBM team,
and
A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo,
and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team,
report:
The short-duration GRB 190728A (The Fermi GBM team, GCN Circ. 25181)
has been detected by Fermi (GBM trigger 585988241) and
INTEGRAL (SPI-ACS), so far, at about 23437 s UT (06:30:37).
We have triangulated this GRB to a GBM-INTEGRAL annulus centered at
RA(2000)=82.621 deg (05h 30m 29s) Dec(2000)=-46.530 deg (-46d 31' 49"),
whose radius is 86.613 +/- 1.356 deg (3 sigma).
The IPN localization is consistent with, but reduces the area of, the
Fermi GBM one.
This localization may be improved.
This burst is spatially and temporally (occurred ~14 min before)
inconsistent with LIGO/Virgo S190728q.
