- Аннотация: MASTER OT J034412.48-263556.5 discovery - PSN in 0"W,21"S of PGC134086 MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 03h 44m 12.48s -26d 35m 56.5s on 2017-11-06.23799 UT during IPN Fermi soft short GRB171030A (Fermi T_trig=2017-10-30 17:29:45.12 UT, Hamburg et al. GCN #22079, Kozlova et al. GCN #22076, Kienlin et al. GCN #21520) inspection by MASTER Global Robotic Net (Lipunov et al. GCN #22080 , Lipunov et al. GCN#22102 ) . This was soft short GRB, that can be off-axis gamma emission, produced by near (<50-100 Mpc) Neutron Stars merging (Burgess et al., Viewing short Gamma-ray Bursts from a different angles, arXiv:1710.05823 https://arxiv.org/abs/1710.05823 ). The OT unfiltered magnitude is 18.7m (mlim=18.7m). This PSN is in 0"W,21"S of PGC134086 (Btc=16.2, V_GSR,LG=19958km/s, M_B=-21.1+-0.9 ) There are 5 images with PSN: 2017-11-06 05:27:16UT - 2017-11-06 07:42:22UT We have reference images without OT on 2017-09-27.19196 UT with unfiltered magnitude limit 20.1m, on 2017-11-03 06:18:44 with mlim=17.7. Spectral observations are required. The discovery and reference images are available at http://master.sai.msu.ru/static/OT/034412.48-263556.5.png
