Scoperta del sistema EW CMC15 J172246.1-043401

Ecco scoperto un nuovo sistema EW: si tratta di CMC15 J172246.1-043401 in Ofiuco, scoperto, al solito, grazie all’utilizzo del telescopio dell’Osservatorio Astronomico dell’Università di Siena e il supporto, come al solito indispensabile di Riccardo Papini ed Alessandro Marchini. L’escursione di luminosità va dalla 15.83 alla 16.45 CV. Epoca: 2457889.5333 HJD Periodo: 0.315587 d Ecco il link al VSX: https://www.aavso.org/vsx/index.php?view=detail.top&oid=477889 […]
