Аннотация:MASTER OT J174705.64-523632.4 detection
Following ATEL #10721 by R.Ojha et al. MASTER-SAAO inspected 4 sq.deg. with the center of RA(2000)=17 47 05.7 -52 36 32.5 on 2017-09-14 17:29:13.163UT
MASTER auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) detected optical transient at the position RA(2000) = 17 47 05.64 -52 36 32.4 with unfiltered m_OT=16.8
We analyzed MASTER-OAFA and MASTER-SAAO databases. There was no optical sources at this position (unfiltered upper limit) on
