- Аннотация: MASTER OT J034412.48-263556.5 - OT inside IPN/Fermi GRB171030A MASTER OT J034412.48-263556.5 SN (Lipunov et al., ATEL #10929 ; Lipunov et al. GCN #22102) is inside common area of IPN/Fermi GRB171030A with NSs merging rate MAP inside local 50 Mpc distance. the situation map is available at http://observ.pereplet.ru/images/VLNSmergrate.jpg (see Lipunov, V. et al., GCN #22080 , Lipunov et al. "The gravitational wave sky, Astronomy and Astrophysics, v.298, p.677, 1995; Lipunov et al., 2017, https://arxiv.org/ftp/arxiv/papers/1710/1710.05911.pdf ). This OT was observed by X.Wang at Lijiang 2.4m telescope (spectrum with YFOSC+G3) and shows blue and featureless continuum like GRB170817A (Kilonova), but much brighter (Xiaofeng Wang et al. GCN #22108) The second Spectrum was taken by D.Sahu at 2-m aperture optical-infrared telescope, the Himalayan Chandra Telescope (HCT) with HFOSC (Hanle Faint Object Spectrograph Camera https://www.iiap.res.in//iao/hfosc.html ) at Indian Astronomical Observatory on 2017-11-08 12:58:44UT, with total exposition 3600s. MASTER-OAFA observed it on 2017-11-08 08:14:31.18UT with unfiltered m_OT=19.3+-0.3 Deep photometry and Spectrum are required.
