The Fermi GBM team reports the detection of a likely LONG GRB
At 14:34:38 UT on 5 Jun 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240605C (trigger 739290883.214644 / 240605607).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 231.5, Dec = -74.4 (J2000 degrees, equivalent to J2000 15h 26m, -74d 24'), with a statistical uncertainty of 1.2 degrees.
The angle from the Fermi LAT boresight is 167.0 degrees.

MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 240605C ( Fermi GBM team, GCN 36619) errorbox 7196 sec after notice time and 7229 sec after trigger time at 2024-06-05 16:35:07 UT, with upper limit up to 18.0 mag. Observations started at twilight. The observations began at zenith distance = 52 deg. The sun altitude is -11.3 deg.
The galactic latitude b = -15 deg., longitude l = 313 deg.
Real time updated cover map and OT discovered available here:
