Alert Notice 419: Nova eruption in V407 Cyg

March 15, 2010: 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.
