Per il momento in mancanza di designazione le osservazioni vanno inviate ad AAVSO con il nome NOVA Cyg 20014	+	Riporto qui Alert AAVSO per seconda Nova in Ofiuco

Obs., University of Hyogo, Japan), by K. Ayani (Bisei Astron. Obs., Ibara, Okayama, Japan), and by M.

-	Spettri a bassa risoluzione della stella hanno rivelato trattarsi di una classica nova FE II-tipo past massimo. Scesa nei giorni scorsi alla 11.5V è risalita alla 9.8V.
