UniSi_V113: new EW system

This one was VERY hard. Due the presence of a star at 11″ with a similar magnitude from the target, was really difficult to deblend the ASAS-SN survey’s data. This is the UniSi_V113 (UCAC4 763-005062 in Cassiopeia) and was firstly discovered on October 2017 at the telescope of Astronomical Observatory of University of Siena by Fabio Salvaggio, Alessandro Marchini and Riccardo Papini. Absolutely important was the effort of Davide Agnetti to get the right period during many follow-up observations.

Magnitude variation goes from 15.00 to 15.17 V.

Epoch: HJD 2458011.493
Period: 0.34154 d
