After almost two years from when we found the variability of this star (August 29, 2017), we can announce the UniSi_V116 (UCAC4 760-020578 in Cassiopeia) discovered with the telescoper of Astronomical Observatory of University of Siena by Fabio Salvaggio, Nello Ruocco, Alessandro Marchini, Riccardo Papini, Massimo Banfi.
We observed this target during 8 nights (1 UniSi, 2 WBRO, 5 Nastro Verde) to reach the full phase (at that magnitude was impossible to find useful data from surveys).
UniSi_V116 it’s a typical EW system.
Magnitude variations goes from 16.45 to 16.83 CV.
Epoch: HJD 2458721.392
Period: 0.334802 d
