论文摘要
M31复发Nova M31N 1926-07C有五次记录的爆发。列出了两次最新爆发的浅色曲线，即2020年1月（M31N 2020-01b）和2022年9月（M31N 2022-09A），表明这两个事件的光度演变非常相似，高峰幅度为$ R = 17.2 \ pm0.1 $和$ $ $ $ r = 17.1 $ teem = 17.1 $ teem = 17.1 $ = 17.1 $ = 17.1 c。 $ 9.7 \ pm0.9 $和$ 8.1 \ pm0.5 $ $天数分别为2020年和2022年爆发。在考虑了最近的四次爆发的日期（据信周期计数）之后，发现了$ \ langle p_ \ mathrm {rec} \ rangle = 2.78 \ pm0.03 $年的平均复发间隔，并确定M31N 1926-07C已知的M31N 1926-07C已知。
The M31 recurrent nova M31N 1926-07c has had five recorded eruptions. Well-sampled light curves of the two most recent outbursts, in January of 2020 (M31N 2020-01b) and September 2022 (M31N 2022-09a), are presented showing that the photometric evolution of the two events were quite similar, with peak magnitudes of $R=17.2\pm0.1$ and $R=17.1\pm0.1$, and $t_2$ times of $9.7\pm0.9$ and $8.1\pm0.5$ days for the 2020 and 2022 eruptions, respectively. After considering the dates of the four most recent eruptions (where the cycle count is believed to be known), a mean recurrence interval of $\langle P_\mathrm{rec}\rangle=2.78\pm0.03$ years is found, establishing that M31N 1926-07c has one of the shortest recurrence times known.
