After five months, we back to discover variable stars. And this is the first (real, not imported) post in my new website.
The new variable star is the UCAC4 590-041015 in Gemini. We – with Alessandro Marchini and Riccardo Papini – discovered this system on 16 january 2016. But it was really difficult to complete the analysis without other observations. So, we asked help to the friends of SSV-UAI (Variable Star section – Unione Astrofili Italiani): Luca Rizzuti, Claudio Lopresti, Massimo Banfi, Lorenzo Barbieri, Giorgio Bianciardi, coordinated by Claudio Arena accomplished the mission!
We also used the ASAS-SN survey data.
Magnitude goes from 15.53 to 16.30 V, with a secondary minima at 15.71 V.
Epoch: 2457404.4140 HJD
Period: 4.903283 d
