UniSi_V115: EW system

This new system has been discovered on the first day of this year. But it needed more observations due to better characterize its behavior.
The UniSi_V115 (UCAC4 533-040998 in Gemini), a EW system, has been discovered at the telescope of the Astronomical Observatory of University of Siena, with a strong collaboration between Alessandro Marchini, Fabio Salvaggio, Riccardo Papini, Massimo Banfi, Pietro Aceti and Davide Agnetti.
ASAS-SN survey data has been used due to better define the period. Magnitudes were deblended from noise derived from a 16″ star.

Magnitude variation goes from 15.87 to 16.32 V.

Epoch: HJD 2458528.3858
Period: 0.365957 d
