According to CBAT's Unconfirmed Observations Page, a new possible
nova has been reported in Cyg (mag = 7.7C).
It is noteworthy that the prenova was recorded in IPHAS survey of
emission line stars.
194301.9 +321913 (2000.0) IPHAS_J194301.98+321913.5 em R=18.174 R-I=0.651 R-Ha=0.631 MNRAS384,1277
The likely ROSAT identifications:
194301.2 +321908 (2000.0) 1WGAJ1943.0+3219 0.0247 0.15 1.26 1.06 0.42 obs=1993.278

194302.1 +321905 (2000.0) 1RXPJ194302+3219.1 0.0260 0.98 0.10
The object is thus potentially a nearby CV undergoing a nova outburst,
or was bright at the epoch of ROSAT observations (cf. V2487 Oph).
If the object was caught during the rise, it might become a naked-eye nova.
