TITLE: GCN CIRCULAR
NUMBER: 24393
SUBJECT: IPN triangulation of GRB 190504A (short)
DATE: 19/05/05 01:20:57 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,
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 190504A has been detected
by Fermi (GBM trigger 578679393) and INTEGRAL (SPI-ACS), so far,
at about 58588 s UT (16:16:28).
We have triangulated this GRB to a GBM-INTEGRAL annulus centered at
RA(2000)=282.762 deg (18h 51m 03s) Dec(2000)=+33.543 deg (+33d 32' 34"),
whose radius is 87.799 +/- 10.241 deg (3 sigma).
The annulus is inconsistent with the high-energy neutrino candidate
event IceCube-190503A (IceCube Collaboration GCN Circ. 24378).
This annulus may be improved.
