- Аннотация: https://gcn.nasa.gov/circulars/42211The MASTER-OAFA robotic telescope of the MASTER Global Robotic Net [1,2,3,4]started Swift GRB 251011B(Ttrigger=2025-10-11 07:08:22UT; XRT RA,Dec(2000)=00h 52m 56.33s,-62d 02'00.2" GCN 42197, GCN 42201)alert observations at 2025-10-11 07:09:27 and observed it up to sunrise (Balanutsa et al. GCN 42203).Next night MASTER automatic planner continued Fermi error-box (GCN 32196) inspection as independent alertMASTER OT J011025.98-583210.6 discoveryMASTER-OAFA auto-detection system of MASTER Global Robotic Net [1,2,3,4]during Fermi GRB 251011B (GCN42204, also detected by Swift (GCN42197) and observed by MASTER in alert mode (GCN 42203)) inspection discovered OT source at (RA, Dec) = 01h 10m 25.98s -58d 32m 10.6s on 2025-10-12.16208 UTwith light curve, that is typical for gamma-ray bursts optical counterpart.The OT unfiltered magnitud m=17.8 (first image) at 2025-10-12 03:53:24UT (mlim=19.3 at single image).The OT is seen in 8 images with typical GRB counterpart decay. There is no minor planet at this place.We have reference image on 2025-09-16.19346 UT with unfiltered mlim=20.3m.So as the Ttrigger for GRB 251011B was 19h earlier our discovery time (2025-10-11 07:08:22.33UT) and Swift error-box center was at 00h 52m 56.33s -62d 02' 00.2" (Swift GCN 42197, GCN 42201)MASTER OT looks not connected with just GRB 251011B, but can be the orphan one [5].Spectral observations and deep photometry are required.[1] Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L[2] Lipunov et al. 2022, Universe, Vol. 8(5), id.271[3] Lipunov et a. 2019, ARep, vol.63, 293[4] Lipunov V., Kornilov V., Gorbovskoy E., Tiurina N., Kuznetsov A. 2023, Astronomical Robotic Networks and Operative Multichanel Astrophysics,Lomonosov MSU PRESS, 591pp.http://www.pereplet.ru/lipunov/625.html#625[5] Lipunov et al. 2022, MNRAS, 516, 4980 https://ui.adsabs.harvard.edu/abs/2022MNRAS.516.4980L/abstract
