A new EW system in Ophiuchus has been discovered.
We saw it, at first time, in may. But we finisched the work just last week. The discovery is made with my Brothers-in-star Alessandro Marchini e Riccardo Papini and the collaboration with friends Mauro Bachini and Giacomo Succi.
We also used CRTS data to improve period calculation.
Magnitude variations goes from 15.03 to 15.47 CV.
