Classical Nova. Classical novae (CN) are a class of nova and cataclysmic variable that have only a single observed eruption. Typical brightness ranges for CN range from 6 to greater than 19 magnitudes. Brighter novae have shorter durations than dimmer novae. CN outbursts are usually modelled as thermonuclear runaways originating in.

A cataclysmic variable which has only been seen to erupt once is known as a classical nova.During outburst, the brightness of these novae can increase by 6 to 19 magnitudes before fading back to the original level. The outbursts themselves can last anywhere from several days to years, but in general, the brighter the nova, the shorter its duration.
