The Fermi GBM team reports the detection of a likely LONG GRB
At 14:41:18 UT on 15 Feb 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230215A (trigger 698164883.649682 / 230215612).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 353.0, Dec = -5.1 (J2000 degrees, equivalent to J2000 23h 32m, -5d 05'), with a statistical uncertainty of 10.1 degrees.
The angle from the Fermi LAT boresight is 73.0 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 230215A ( Fermi GBM team, GCN 33326) errorbox 14520 sec after notice time and 14555 sec after trigger time at 2023-02-15 18:43:53 UT, with upper limit up to 16.7 mag. Observations started at twilight. The observations began at zenith distance = 79 deg. The sun altitude is -15.6 deg.
The galactic latitude b = -61 deg., longitude l = 80 deg.
