GRB 190720B: Fermi GBM Final Real-time Localization
2019-07-20T23:20:09Z (5 years ago)
Fermi GBM Team at MSFC/Fermi-GBM <>
The Fermi GBM team reports the detection of a likely LONG GRB

At 23:08:38 UT on 20 Jul 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190720B (trigger 585356923.763906 / 190720964).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 138.9, Dec = -55.6 (J2000 degrees, equivalent to J2000 09h 15m, -55d 36'), with a statistical uncertainty of 2.4 degrees.

The angle from the Fermi LAT boresight is 54.0 degrees.
