tells how Leslie Peltier missed the second outburst of T CrB because he had a cold the night it lit up, after observing it religiously for many years. It also tells how Gary Poyner "disqualified" CI Aql as a recurrent nova just weeks before its second outburst.
How are RN "suspected" as such before their second outburst? Is it something in the spectrum? Or is it the lower amplitude of the outburst?
