UniSi_V111: new EW system discovered

This is UniSi_V111 (GSC 02382-00788 in Auriga), a nice EW system discovered in october 2017 with the telescope of Astronomical Observatory of University of Siena with Alessandro Marchini, Fabio Salvaggio and Riccardo Papini, but needed a lot of time ad observations (thanks to Davide Agnetti!) to be characterized.

Of course, ASAS-SN survey was a grat help.

The magnitude variation goes from 15.27 to 15.57 V.

Epoch: HJD 2458467.5092
