MASTER OT J144927.01-324406.8 - New Dwarf Nova with binary period determination
MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) 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.
