MASTER OT J070559.93-381358.7 - the optical flare discovery of X-ray source

MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered optical flare of the source at (RA, Dec) = 07h 05m 59.93s -38d 13m 58.7s on 2015-03-06.87322 UT. The OT unfiltered magnitude is 15.0m (the limit is 19.0m).

The OT is seen in 5 images on 2015-03-06.

We have 2 images of this OT with m_OT=15.7 on 2015-01-14.0569UT.

We have reference image with m_OT=19.8 on 2014-12-24.97509 UT (with 19.9 unfiltered magnitude limit).

This OT has X-ray assotiation with J070600.0-381357 Swift source from SXPS Swift X-ray telescope point source catalogue (Evans+ 2014).

The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/070559.93-381358.7.png

Spectral observations are required.
