UCAC4 552-028220 – EA System discovery

Poker! Another variable star has been discovered by the team composed by me, Massimo Banfi and Riccardo Papini (WBRO – K49) and Alessandro Marchini (Astronomical Observatory of University of Siena).

This is the UCAC4 552-028220 located in Gemini, a very nice EA semi-detached system that seems almost an EB system. We covered almost all phase period and refined the period using the ASAS-SN data.

Magnitude goes from 14.78 to 15.33 V, with a secondary minima at 14.99 V.

Epoch: 2458136.4150 HJD
Period: 0.679907 d
