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.
