Nova eruption in V407 Cyg
Abstract:
According to CBET 2199, 2204, and 2205, the suspected symbiotic star V407 Cyg has been observed in an anomalously bright outburst, and subsequent spectroscopic observations by multiple observers show clear signs of a classical nova. Observations of this anomalous event are requested immediately, and observers are asked to continue observing this object until it returns to its previous quiescent level.
Justification:
In summary, the evidence points to a classical nova eruption of a symbiotic star. The system is further complicated by the fact that the donor star in the system is likely a variable of Mira type. All observations of this complex and interesting system, including visual estimates, CCD time series, and multicolor photometry are strongly encouraged.
