LIGO/Virgo G274296: Global MASTER Net two OTs detection
Abstract
MASTER-Tunka (Sibiriya, Baykal, -30C)detected two additional OTs during LIGO/VIRGO alert inspection (Peter Shawhan, GCN 20689; Lipunov et al., GCN 20696). MASTER OT J111410.86+383448.2 - AGN. MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 11h 14m 10.86s +38d 34m 48.2s on 2017-02-18.77808 UT. The OT unfiltered magnitude is 18.6m (limit 19.6m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2011-04-23.66288 UT with unfiltered magnitude limit 20.2m. There is object SDSS DR10 catalogue of candidate quasars (Brescia+, 2015, 2015MNRAS.450.3893B ) Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/111410.86383448.2.png MASTER OT J104314.39+241518.4 - PSN in the SDSS galaxy with ~4 arcsec offset. MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 10h 43m 14.39s +24d 15m 18.4s on 2017-02-18.73677 UT. The OT unfiltered magnitude is 18.8m (limit 19.3m). The OT is seen in 1 image. There is no minor planet at this place. We have reference image without OT on 2011-03-30.69752 UT with unfiltered magnitude limit 20.4m. THERE is SDSS galaxy J104314.36+241522.4 in 4 arcsec from OT. Spectral observations are required.
