MASTER OT J144927.01-324406.8  - New Dwarf Nova with binary period determination

MASTER-SAAO auto-detection system  (  <A HREF="http://www.hindawi.com/journals/aa/2010/34917
1/">Lipunov
et al., Advances in Astronomy, MASTER Global Robotic Net, 2010</A> ) discovered
OT source at (RA, Dec) = 14h 49m 27.01s -32d 44m 06.8s on 2015-08-09.71103
UT. 

The OT unfiltered magnitude is 
14.5m
(the limit is 18.7m). The OT  is seen in 192 images. There is no minor
planet at this place. 

The binary period P ~ 0.075d = 108 min. The light curve is available at
http://master.sai.msu.ru/static/OT/MASTER_OT_J144927.01_324406.8.jpg  

There is GALEX source at this place.  

Spectral observations are required.
