GRB 200320A: Fermi GBM Final Localization
2020-03-20T15:45:19Z (4 years ago)
Joshua Wood at MSFC/Fermi-GBM <>
The Fermi GBM team reports the detection of a likely Long GRB.

At 09:56:46 UT on 20 Mar 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200320A (trigger 606391011 / 200320414). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 184.3, Dec = -38.7 (J2000 degrees, equivalent to J2000 12h 17m, -38d 42'), with a statistical uncertainty of 3.4 degrees. The angle from the Fermi LAT boresight is 79.0 degrees.
