SUBJECT: GRB 190630A: Fermi GBM Final Real-time Localization
DATE: 19/06/30 06:21:40 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely SHORT GRB
At 06:09:58 UT on 30 Jun 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190630A (trigger 583567803.319036 / 190630257).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 307.0, Dec = -1.3 (J2000 degrees, equivalent to J2000 20h 27m, -1d 18'), with a statistical uncertainty of 7.7 degrees.
The angle from the Fermi LAT boresight is 48.0 degrees.

and
S. Xiao, C. K. Li, X. B. Li, Y. Huang, and S. L. Xiong
on behalf of the Insight-HXMT GRB team,
report:
The short-duration GRB 190630A was detected
by Fermi (GBM trigger 583567803), INTEGRAL (SPI-ACS),
and Insight (HXMT/HE) at about 22198 s UT (06:09:58).
We have triangulated this GRB to a GBM-INTEGRAL annulus centered at
RA(2000)=32.604 deg (02h 10m 25s) Dec(2000)=-47.005 deg (-47d 00' 16"),
whose radius is 73.654 +/- 2.609 deg (3 sigma).
The annulus is partially consistent with the 90% localization
probability region of GW compact binary merger candidate
event S190630ag (The LIGO Scientific Collaboration and the Virgo
Collaboration GCN Circ. 24922).
This annulus may be improved.
