LIGO/Virgo G275404: MASTER bright OT detection
Abstract
MASTER OT J105958.00-115756.5 - possble new CV ? MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 10h 59m 58.00s -11d 57m 56.5s on 2017-02-25.96032 UT during LIGO/Virgo G275404 (GCN 20738). The OT unfiltered magnitude is 17.1m (mlim = 20.0). The OT is seen in 2 images. There is no minor planet at this place. We have reference image on 2015-05-17.82159 UT with unfiltered mlim= 20.0m. There is GALEX-DR5 source in half pixel offset. Spectral observations are required.
