Ljuskurva för NO Apodis, plottad från Hipparcosdata. Uppgifterna har visats med den 24,9-dygnsperiod som anges i International Variable Star Index.[2]
NO Apodis klassificeras som en halvregelbunden variabel av okänd undertyp. Observationer av Tabur et. al. (2009) visar att den har två perioder, båda varar 26-7 dygn.[16] Inom denna tidsram varierar stjärnans skenbara magnitud mellan 5,71 och 5,95 i det visuella bandet.[2]
