- Аннотация: https://gcn.nasa.gov/circulars/41996The MASTER-OAFA robotic wide-field camera, located in Argentina (OAFA observatory of San Juan National University [1], during a regular survey, obtained an image of the region of the sky containing the point with coordinates MASTER OT J195412.89-485016.4 (GCN 41893) and source (Li et al., GCN 41877) before, during and after the Fermi trigger moment (GBM GCN 41874, GCN 41876, GCN 41890; LAT GCN 41884, Ttrigger=00:28:52) of GRB 250919A .Very bright optical counterpart MASTER OT J195412.89-485016.4promptly detected at the agnitude ~ 9 m.This transient was first publishied as EP250919a optical counterpart by LasCumbres observatory (GCN 41877, t_detection=03:02:52.800 UTC)and as Fermi GRB 250919A/EP250919a optical counterpart by Gemini-South (LEvan etal. GCN 41883) with reshift detection z = 1.145
